PRIN Bando 2022<\/span> \u00a0<\/p>\n \u00a0<\/p>\n + Large Universal Electroweak Corrections: automated, fast and precise (PRIN_2022EZ3S3F)<\/span>- Large Universal Electroweak Corrections: automated, fast and precise (PRIN_2022EZ3S3F)<\/span> The High-Luminosity Large Hadron Collider (HL-LHC) and the future generation of hadron and lepton colliders will probe the Standard Model (SM) with unprecedented precision and extend the exploration of particle interactions into previously inaccessible energy regimes. To fully exploit their physics potential, theoretical predictions must achieve a level of accuracy comparable to, or exceeding, the experimental one. In this context, electroweak (EW) radiative corrections constitute one of the main frontiers of precision collider phenomenology.<\/span><\/p>\n While next-to-leading-order (NLO) EW corrections can nowadays be computed in a largely automated way, their efficient incorporation into realistic event simulations and their consistent combination with QCD and QED radiation remain open challenges. Moreover, at energies well above the electroweak scale, EW corrections are dominated by Sudakov logarithms of the ratio between the hard-scattering scale and the weak-boson masses. These logarithmically enhanced contributions can reach tens of percent at the TeV scale and therefore represent a crucial ingredient for precision studies at the HL-LHC and future colliders.<\/span><\/p>\n The project aims at developing a comprehensive framework for the calculation, implementation and phenomenological exploitation of electroweak Sudakov effects. The research programme is structured around three main objectives: (i) the implementation of the dominant EW effects in Monte Carlo event generators, enabling fast and accurate simulations combined with QCD dynamics; (ii) the study of EW corrections in the multi-TeV regime relevant for future hadron and lepton colliders; and (iii) the extension of these techniques to scenarios beyond the Standard Model.<\/span><\/p>\n The project builds upon recent advances in the theoretical understanding of electroweak Sudakov logarithms and their implementation within automated frameworks such as MadGraph5_aMC@NLO. Its outcome will provide novel theoretical tools and precision predictions for current and future collider experiments, strengthening the capability of the high-energy physics programme to test the Standard Model and search for new phenomena.<\/span><\/p>\n \u00a0<\/p>\n <\/div><\/span><\/p>\n\n\n\n + High performance microelectronics for low-noise cryogenic applications (PRIN_2022ZE4759)<\/span>- High performance microelectronics for low-noise cryogenic applications (PRIN_2022ZE4759)<\/span> Modern dark matter and neutrino physics experiments, such as DUNE, rely on massive underground detectors operating at extreme cryogenic temperatures around -200\u00b0 C. A major technological bottleneck is that commercial electronics perform unpredictably in these environments, and standard silicon foundries do not provide the raw technical parameter models needed to simulate layouts under such cold conditions. \u00a0<\/p>\n <\/div><\/span><\/p>\n\n\n\n + Beauty Probes of quantUm chromoDynamics (PRIN_202258ASA7)<\/span>- Beauty Probes of quantUm chromoDynamics (PRIN_202258ASA7)<\/span> BE PROUD focuses on measurements of W and Z boson production in association with b-quark jets, using the full ATLAS Run 2 dataset (pp collisions at \u221as = 13 TeV, ~140 fb\u207b\u00b9). These processes test perturbative QCD in a kinematically challenging regime where multiple energy scales coexist, and are also important backgrounds for Higgs boson measurements and New Physics searches. The project covers four work packages: a measurement of Z+b-jets in the boosted regime, the first differential cross-section measurement of W+\u22652b-jets at 13 TeV, a precision study exploiting the ttbar+b-jets \/ Z+b-jets cross-section ratio to cancel common systematic uncertainties, and outreach activities.<\/span><\/p>\n Results will provide key inputs for Monte Carlo tuning, global PDF fits, and Effective Field Theory analyses.<\/span><\/p>\n \u00a0<\/p>\n <\/div><\/span><\/p>\n\n\n\n + Imaging calorimetry in scintillating media for high energy physics and tomography (PRIN_2022KJZSYB)<\/span>- Imaging calorimetry in scintillating media for high energy physics and tomography (PRIN_2022KJZSYB)<\/span> This research project explores the use of scintillation light imaging to detect ionizing particle interactions, primarily in cryogenic noble liquid scintillators.<\/span><\/p>\n The formation of an image on a sensor matrix (built with Silicon Photomultipliers) through a coded aperture mask allows to reconstruct the event topology and the deposited energy.<\/span><\/p>\n This technique is proposed as an alternative or a complement to the traditional charge based readout of LAr and LXe TPCs, bringing the advantage of a higher rate capability.<\/span><\/p>\n Its potential applications to other scintillators, to be used in the construction of calorimeters or medical imaging devices will also be explored.<\/span><\/p>\n \u00a0<\/p>\n <\/div><\/span><\/p>\n\n\n\n +Development of innovative scintillation detector for future particle colliders and medical imaging (PRIN_2022MHC2MH)<\/span>-Development of innovative scintillation detector for future particle colliders and medical imaging (PRIN_2022MHC2MH)<\/span> Since the discovery of X-rays at the end of the 19th century, the continuous technology transfer from High-Energy Physics (HEP) to medical imaging represents one of the most successful examples of how fundamental research impacts our society. Seeking answers to the fundamental questions about the smallest constituents of the universe and the rules governing their interaction, HEP researchers developed technological innovations that improved dramatically also our capabilities to study the human body.<\/span><\/p>\n This project aims at developing technological solutions to be adopted for calorimeters operating at the next generation of HEP experiments. Radiation tolerance, granularity, capability to operate at extreme rates, and spatial and timing resolution, well beyond the limit of current detectors, will be mandatory to cope with the conditions imposed by future accelerators. Improvements to all the components of modern calorimeters will be studied, with particular attention to new scintillating crystals with optimised properties, very fast photomultiplier and dedicated readout electronics. Building on top of the gained experience the project will investigate the possibility to use the developed technologies for time-of-flight measurements in PET devices for medical imaging.<\/span><\/p>\n \u00a0<\/p>\n <\/div><\/span><\/p>\n\n\n\n +New physics, fundamental engineering and technological challenges in the emerging era of neutrino detectors at the Large Hadron Collider: feasibility study in view of an upgrade of the SND@LHC experiment for the high-luminosity LHC (PRIN_2022E4JFWF)<\/span>-New physics, fundamental engineering and technological challenges in the emerging era of neutrino detectors at the Large Hadron Collider: feasibility study in view of an upgrade of the SND@LHC experiment for the high-luminosity LHC (PRIN_2022E4JFWF)<\/span> A new branch of neutrino physics has started in 2022. For the first time, pioneer experiments, like SND@LHC, were built at CERN to detect neutrinos produced at the LHC, in a hitherto unexplored angular region and in a very high energy domain where the cross-sections remain totally unexplored, in particular for tau neutrinos where new physics may be unveiled. First observations have recently been published.<\/span><\/p>\n An advanced version of SND@LHC (called AdvSND) will have to be designed to extend the physics program in the LHC high luminosity phase (HL-LHC), scheduled to start in 2029. Three key points need to be investigated as a prelude to a design, and are the subject of this PRIN.<\/span><\/p>\n Work Package 1 ( INFN Bologna leading) is dedicated to searching the LHC tunnel for a location to install a second apparatus for measuring neutrinos in an angular region that partially overlaps with the LHCb experiment. This possibility will reduce the systematic uncertainties of the AdvSND measurements, and maximize the statistical accuracy reachable at HL-LHC. The underground location will have to show sustainable machine-induced backgrounds.<\/span><\/p>\n In Work Package 2 (University Parthenope of Naples leading), a state-of-the-art magnet is studied for placement downstream of the AdvSND setup, so to enable distinguishing between neutrinos and anti-neutrinos interactions.<\/span><\/p>\n Work Package 3 (University Federico II of Naples leading) consists in identifying new detector technologies to profit from the HL-LHC. In particular, a new vertex detector has to be designed for AdvSND using silicon detectors or other real time devices, since the emulsion technology of SND@LHC cannot operate in the HL-LHC environment.<\/span><\/p>\n \u00a0<\/p>\n <\/div><\/span><\/p>\n\n\n\n +Beyond Liquid Argon (BeLAr): a Xenon Doped LArTPC forNeutrinoless Double Beta Decay Searches (PRIN_2022STFALX)<\/span>-Beyond Liquid Argon (BeLAr): a Xenon Doped LArTPC forNeutrinoless Double Beta Decay Searches (PRIN_2022STFALX)<\/span> The aim of BeLAr is to transform the DUNE experiment into the most sensitive neutrinoless double beta decay (0\u03bd\u03b2\u03b2) observatory in the world. This can be achieved by capitalizing on two major experimental results: the capability of building a LArTPC with a significant amount of Xe-136 as part of the WLS compound; and the direct detection of xenon scintillation light. We want to prove such a bold statement by building a small-scale xenon doped LArTPC at CERN to demonstrate the effectiveness of xenon doping and by performing a data-driven assessment of background mitigation<\/span><\/p>\n \u00a0<\/p>\n <\/div><\/span><\/p>\n\n\n\n +A fast lens based imaging device for liquid argon detectors for neutrino, particle, and medical physics applications (PRIN_2022M7RRKK)<\/span>-A fast lens based imaging device for liquid argon detectors for neutrino, particle, and medical physics applications (PRIN_2022M7RRKK)<\/span> The project aims to demonstrate the feasibility of obtaining temporal and spatial information of particle interactions in liquid argon detectors, using devices that produce stereoscopic images of the ultraviolet light copiously emitted by liquid argon. The key idea is to use a lens system coupled to a high-granularity photon detector, a novel approach in particle physics. The project plans to build prototypes that address the technological challenges and test them with cosmic rays. If the project succeeds, it will offer a faster, simpler and cheaper alternative to the current methods, based on time projection chambers, and will have an impact on neutrino physics, dark matter, and beta decay. The project also has potential applications in biomedical devices, such as a new PET machine for tumor detection for a full-body detector with a low dose for patient.<\/span><\/p>\n \u00a0<\/p>\n <\/div><\/span><\/p>\n\n\n\n +Towards the ultimate Dark Matter experiment: improved electrodes and neutron veto technologies for the next-generation xenon TPC for the direct detection of dark matter (PRIN_2022YYX3WJ)<\/span>-Towards the ultimate Dark Matter experiment: improved electrodes and neutron veto technologies for the next-generation xenon TPC for the direct detection of dark matter (PRIN_2022YYX3WJ)<\/span> The project lays in the field of direct dark matter search, where the current best results come from the XENON esperiment at the INFN Gran Sasso Underground Laboratory. Neutrons represent one of the most important background in this search: one way to mitigate their impact is by using an active veto all around the xenon target made of a Gd-doped water Cherenkov detector.<\/span><\/p>\n The project aims at improving the performances of this kind of veto, increasing the Gd concentration, the transparency of the solution, and the salt recovery at the end of the operations, in view of the next phase of the XENON experiment, named DARWIN.<\/span><\/p>\n \u00a0<\/p>\n <\/div><\/span><\/p>\n","protected":false},"excerpt":{"rendered":" \u00a0 \u00a0 PRIN Bando 2022 \u00a0 \u00a0<\/p>\n","protected":false},"author":24,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"template-page-builder-no-sidebar.php","meta":{"_lmt_disableupdate":"no","_lmt_disable":"","footnotes":""},"class_list":["post-42789","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"\/amministrazione\/wp-json\/wp\/v2\/pages\/42789","targetHints":{"allow":["GET"]}}],"collection":[{"href":"\/amministrazione\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"\/amministrazione\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"\/amministrazione\/wp-json\/wp\/v2\/users\/24"}],"replies":[{"embeddable":true,"href":"\/amministrazione\/wp-json\/wp\/v2\/comments?post=42789"}],"version-history":[{"count":50,"href":"\/amministrazione\/wp-json\/wp\/v2\/pages\/42789\/revisions"}],"predecessor-version":[{"id":43861,"href":"\/amministrazione\/wp-json\/wp\/v2\/pages\/42789\/revisions\/43861"}],"wp:attachment":[{"href":"\/amministrazione\/wp-json\/wp\/v2\/media?parent=42789"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

The project focuses on establishing specialized test methodologies and infrastructure to study microelectronic behavior in extreme environments.
Using liquid nitrogen test benches at the INFN-DIFA Cryogenic Laboratory, microelectronic parameters are extracted from prototype ASICs. These measurements update foundry libraries for realistic simulations before eventual manufacturing, leaving room for the potential design or validation of custom blocks.
UniBo manages microelectronic modeling, design environments, and thermal cycles. INFN Bologna is responsible for integration and readout, managing room-temperature digital acquisition systems, designing custom PCBs, and eventually handling the micro-bonding of bare silicon dies. This infrastructure evaluates core electronic blocks interfacing with SiPM arrays, conducting accelerated aging tests to ensure a long lifespan.<\/span><\/p>\n<\/strong><\/span><\/p>\n\n
