Abstract:

A search for heavy neutral gauge bosons (Z0) decaying into a pair of tau leptons is performed in proton-
proton collisions at $\sqrt{s}$ = 13 TeV at the CERN LHC. The data were collected with the CMS detector and
correspond to an integrated luminosity of 138 fb$^{−1}$. 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 Z´
production cross section and its branching fraction to tau lepton pairs for a range of Z´ boson masses. For a
narrow resonance in the sequential standard model scenario, a Z´ boson with a mass below 3.5 TeV is
excluded. This is the most stringent limit to date from this type of search.
