Search for vector-like leptons in multilepton final states in pp collisions at $\sqrt{s} = $ 13 TeV
Abstract: A search for an SU(2) doublet of vector-like leptons with preferential couplings to the third generation standard model leptons is presented studying multilepton final states. The data sample corresponds to 41.4 fb$^{-1}$ of integrated luminosity in pp collisions at $\sqrt{s} = $ 13 TeV collected by the CMS experiment at the Large Hadron Collider in 2017. Events are categorized based on the multiplicity of light leptons and taus. The missing transverse momentum and the scalar sum of transverse momenta of leptons are used to discriminate the signal against standard model backgrounds. The observations are consistent with the expectations from the standard model processes. These results are used to exclude vector-like leptons in the mass range of 130-690 GeV.
