Search for new physics with leptons in the final state

Numerous new physics models predict the existence of heavy particles decaying to leptonic final states. Experimental signatures involving leptons are one of the cleanest probes of new physics at the LHC. This talk presents searches for physics beyond the standard model in final states with leptons (including hadronically decaying tau leptons) with the CMS detector, focusing on the recent results obtained using the data collected during the 2016 proton-proton run of the LHC at the centre of mass energy of 13 TeV.
