Search for heavy neutral resonances decaying to τ lepton pairs in pp collisions at s= 13 TeV
Abstract: A search for heavy neutral gauge bosons (Z') decaying to two tau leptons is performed in proton-proton collisions at s= 13 TeV at the CERN LHC. The data were collected with the CMS detector and correspond to an integrated luminosity of 138 fb1. The yields of candidate events are found to be consistent with the predictions from standard model processes. Limits on the production cross section times branching fraction of the Z' as a function of the Z' mass are set at the 95% confidence level. For a narrow resonance in the sequential standard model scenario, a Z' with mass below 3.5 TeV is excluded. This is the most stringent limit to date from this type of search.
