The three-leptons signature from resonant sneutrino production at the LHC
G. Moreau, E. Perez, G. Polesello
Abstract
The resonant production of sneutrinos at the LHC via the R-parity violating couplings ł'ijk Li Qj Dck is studied through its three-leptons signature. A detailed particle level study of signal and background is performed using a fast simulation of the ATLAS detector. Through the full reconstruction of the cascade decay, a model-independent and precise measurement of the masses of the involved sparticles can be performed. Besides, this signature can be detected in a large part of the SUSY parameter space and for wide ranges of values of several ł'ijk coupling constants.
