Estudio fenomenológico sobre búsquedas de supersimetría en el LHC, usando estados finales de un Leptón, un Jet de radiación de estado inicial y alta pérdida de energía transversal

Abstract

Results on the phenomenological study on searches for new physics in the LHC are presented, using supersymmetric models in the electroweak sector and assuming final states with a lepton (e, μ, τ), an initial state radiation jet and large missing transverse energy. The study was made using simmulated data from supersymmetric models of interest and events coming from the standard model of particles with final states similar to the searched signals. The simmulations were made using the MadGraph software for event generation, Pythia to emulate quark and gluon fragmentation effects (Hadronization processes) and Delphes for detector effects simmulation. The sample analysis was made using C++ in interphase with the Root software. The study presents the event selection criteria to distiguish the signal form standard model processes and thus make the experimental analysis in the LHC.
