Search for heavy resonances decaying to tau lepton pairs in proton-proton collisions at √s=13 TeV

A search for heavy resonances that decay to tau lepton pairs is performed using proton-proton collisions at √ s = 13 TeV. 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...
