The data were collected with the CMS detector at the CERN LHC and correspond to an integrated luminosity of 2.2 fb(-1). The observations are in agreement with standard model predictions. An upper limit at 95% confidence level on the product of the production cross section and branching fraction into tau lepton pairs is calculated as a function of the resonance mass. For the sequential standard model, the presence of Z' bosons decaying into tau lepton pairs is excluded for Z/ masses below 2.1 TeV, extending previous limits for this final state. For the topcolor-assisted technicolor model, which predicts Z' bosons that preferentially couple to third-generation fermions, Z' masses below 1.7 TeV are excluded, representing the most stringent limit to date.eninfo:eu-repo/semantics/openAccessBeyond Standard ModelHadron-Hadron scattering (experimentsParticle and resonance productionSearch for heavy resonances decaying to tau lepton pairs in proton-proton collisions at root s=13 TeVArticle2-s2.0-8501286330610.1007/JHEP02(2017)048Q1Q1WOS:000394322000001
