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".pdfengCIENCIAS FÍSICO MATEMÁTICAS Y CIENCIAS DE LA TIERRAAstrofísicaRelatividad (Física)--InvestigaciónMateria oscura (Astronomía)--InvestigaciónGran colisionador de hadrones (Francia y Suiza)Partículas (Física nuclear)MuonesModelo de QuarkSearch for monotop production in events with one lepton, Missing Transverse Energy, and JetsTesis de licenciaturaopenAccess
