| Abstract: | A search for heavy neutral gauge bosons (πβ²) decaying into a pair of tau leptons is performed in proton-proton collisions at βπ =13ββTeV at the CERN LHC. The data were collected with the CMS detector and correspond to an integrated luminosity of 138ββfbβ1. The observations are found to be in agreement with the expectation from standard model processes. Limits at 95% confidence level are set on the product of the πβ² production cross section and its branching fraction to tau lepton pairs for a range of πβ² boson masses. For a narrow resonance in the sequential standard model scenario, a πβ² boson with a mass below 3.5 TeV is excluded. This is the most stringent limit to date from this type of search. |
