Research Activity

Compact Muon Solenoid (CMS) at the CERN LHC

I carry my research activity in the field of High Energy Physics. Since February 2004 I am member of the Compact Muon Solenoid (CMS) experiment installed along the Large Hadron Collider (LHC) ring at CERN, Geneva. In the years of preparation for the data taking, my main activity in CMS was to design and implement the software tools needed for the data analysis, in particular the muon reconstruction and identification algorithms and the simulation of the response of the drift tube chambers to the transversing particles. After the start of the data taking, having brought the muon reconstruction and identification algorithms to an optimal level of quality and robustness, my interest moved to the searches for new weakly-interacting highly-massive particles, which are candidates to explain the Dark Matter puzzle, and in general to the searches for particles in the framework of the Super-symmetry theories.

Topics

Muon reconstruction algorithms.

SUSY: search for top superpartner in fully hadronic final state (winding down).

Multi-bosons final state analysis. This is an hot topic at LHC, not only because it is a signature of the Higgs boson, but mainly because through that processes we can investigate the electroweak simmetry breaking in very deep details.
