Emphasis is given on the leptonic final states, performed in the muon/electron+jets channels. The search is distinguised based on whether an hadronic tau lepton can be resolved or not. To constrain the backgrounds, the event phase space is categorized in number of jets, b jets and in bins of Emiss T . The search is based on the 13 TeV dataset with 35.9 fb−1 of integrated luminosity collected with the CMS experiment in 2016. Results are presented for charged Higgs boson mass hypotheses ranging from 80 GeV to 3 TeV, where the intermediate mass range around the top quark mass is included. 95% CL upper limits are set on the charged Higgs boson production cross section. A combination with the fully hadronic final state is performed, where combined 95% CL upper limits are set on the charged Higgs boson production cross section. The model independent result is interpreted in the MSSM mmod h benchmark scenario".pdfengCIENCIAS FÍSICO MATEMÁTICAS Y CIENCIAS DE LA TIERRAModelo estándar (Física nuclear)Bosones de Higgs--InvestigaciónColisiones (física nuclear)Particulas (Fisica nuclear)--DecaimientoLeptones (Física nuclear)Tesis de doctoradoopenAccess
