Research Topics


Control System for Drift Tube Chambers in CMS
The Drift Tube Detector in the Barrel region of the CMS detector need a very complex powering system with more than 10000 HV channels (for wires, strips and cathodes) and almost 4000 LV channels for the trigger and read-out electronics. In order to control such large system the official SCADA software chosen by LHC (PVSS) is used. I’ve developed a excellent knowledge of the system, and I’m one of the expert responsible for its hardware maintenance and software development.

Muon Trigger in CMS
In all the experiment at LHC Trigger issues are of key importance for physics analysis, due to the high expected luminosity and the large number of particles generated in an adronic collision. Muons have an important role in selecting events of physics interest, because are present in the final states in many fields of the experiment scientific program (Higgs Boson, Supersimmetry, precise measurement in the Standard Model) and are detectable with good precision and low background.
In CMS the trigger system is subdivided in two steps: a Level-1, realized with a dedicated electronic, and a High Level Trigger, developed with software running on commercial processors. I’ve worked on the L1 Trigger for the muon chambers, first from the hardware point of view, developing and realizing tests for its electronic, then in the commissioning part, working of the effects of noise. Now I’m using this knowledge collaborating in realizing more efficient HLT triggers using muons.

Muon Recostruction in CMS
In the CMS experiment muons are identified and measured by the muon system placed outside the 4T magnet. These information are then used to associate the correct track in the central tracker and from the combined information of the two system it’s possible to improve significantly momentum resolution (under 10% for 1TeV muons). Two long runs with cosmic rays in 2008 and 2009 have been a good test for muon reconstruction in CMS. I’ve worked in the analysis of data collected in 2008, making studies of efficiency, momentum resolution and collaborating in the early steps of the measurement of charge ratio (μ+-) in cosmic rays.

Quarkonium Phisics
Phisics of quarkonium has an important role in the early analysis in CMS due to the large cross section for production of c and b mesons. In particular the channel J/Psi →μ+- will be very useful for calibration of the detector and study of efficiencies with tag and probe methods. Moreover in the last years many new particles have been discovered in the charmonium mass range which are not explained by the theory for charmonium spectrography. These are good candidates of “exotic mesons” predicted in many theories. An interesting state is X(3872) because its mass is near the production threshold of 2 D mesons, so it’s a good candidate to be a “molecular particle”. I’m working in a task force which will first made a confirmation for these particle with CMS, and then will work in better determining its mass and quantum numbers. The channel I’m studying is the decay of direct produced X(3872)→π+-+J/Psi (with J/Psi going into muons), which cross section can be given relatively to the same decay of Psi(2S).

Education


January 2009 – Ongoing
PhD student in Physic at Università degli Studi di Bologna, Bologna, Italy.

March 2008 - September 2004
Master of Science (Laurea Specialistica) in Physics at Università degli Studi di Bologna, Bologna, Italy.
Thesis discussion on 28th March 2008 with final mark: 110/110 “cum laude”.
Thesis Title: Study of the effects of correlated noise on the High Angle Muon Trigger in the CMS Experiment.
Summary: During early commissioning of the Drift Tube muon detector of the CMS experiment a strange pattern of noise was identified, which was characterized from a lot of drift tube giving a signal at the same time.. Various tools has been developed in the CMS framework in order to study in detail the spatial and timing characteristic of this noise, with particular emphasis on the trigger rate generated. The results showed that the rate was not worrisome, gave hits of the possible origine of the noise and tools to keep it checked during the life of the experiment.
Supervisor: Dr. Francesca Romana Cavallo, Dr. Riccardo Travaglini.
University Supervisor: Prof. Antonio Maria Rossi.

July 2004 – September 2000
Bachelor of Science (Laurea Triennale) in Physics, at Università degli Studi di Bologna, Bologna, Italy.
Thesis discussion on 9th July 2004 with final mark: 110/110 “cum laude”.
Thesis Title: Test of electronic devices for the Local Trigger of the Muon Detector in the CMS Experiment.
Summary: The thesis work is focused on the participation in the preparation of the experimental apparatus and the subsequent realization tests on a device called “Server Board”. This is a custom electronic board developed for the trigger system of the Barrel Muon Detector in the CMS experiment. Three kind of test have been performed: a connectivity test - where every data transmission line has been checked using the standard protocol Jtag, a dynamic test - to verify functionality and stability of the board in working conditions, and a “burn in test”, focused on identifying malfunctioning devices. The results obtained on the first delivery of boards made it possible to estimate the impact of malfunctions on the entire production and helped to decide the number of spares needed.
