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.eninfo:eu-repo/semantics/openAccess#BAŞV!Article1111110.1103/PhysRevD.111.1120042-s2.0-105027243729Q1WOS:001516150700007Q10000-0001-6940-78000000-0001-9640-82940000-0003-3742-06930000-0003-3090-29480000-0003-2694-65420000-0002-9514-07990000-0001-6940-7800
