Abstract
"In this research, we study the possibility of detecting new physics phenomena at the Large Hadron Collider (LHC) looking for a leptonic monotop production through flavor changing neutral current channel, in order to confirm a possible Dark Matter particle. Particularly, we focus in events with final states of one lepton, missing transverse energy and at least one single jet tagged as originating form a b-quark. This study consider pp collisions at 13 TeV in centre-of-mass energy with a total integrated luminosity of 35.9 1/fb, which was recorded in 2016. The analysis presented here has been carried out using the CMS official software framework for event generation, simulation, and reconstruction. The search strategy is formulated based on the characteristics of the main kinematics variables. As result, the exclusion limit shows that this kind of signal with a luminosity of 35.9 1/fb can be excluded in a range between 1000 and 2500 GeV, with a cross section bigger than 6 pb".
