Description
My thesis subject aims to search for long-lived decays
of new massive particles in the Compact Muon Solenoid
(CMS) experiment at the Large Hadron Collider (LHC).
CMS is one of the four main experiments at the LHC,
where high energy proton-proton collisions are pro-
duced. New long-lived particles are predicted in several
extensions of the Standard Model (SM). In the model
considered, R-parity violated Minimal SuperSymmetric
Model (RPV-MSSM), the lightest SuperSymmetric par-
ticle (LSP) is long-lived and decays into SM particles.
Therefore, the present goal of my thesis is to reconstruct
the displaced vertex emerging from the decay of the LSP
and set selections to reduce the main backgrounds
