title = "Measurement of the Z / γ∗→ ττ cross section in pp collisions at √s=13TeV and validation of τ lepton analysis techniques",
abstract = "A measurement is presented of the Z / γ∗→ ττ cross section in pp collisions at s=13TeV, using data recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 2.3fb-1. The product of the inclusive cross section and branching fraction is measured to be σ(pp→Z/γ∗+X)B(Z/γ∗→ττ)=1848±12(stat)±67(syst \,+\,lumi) pb, in agreement with the standard model expectation, computed at next-to-next-to-leading order accuracy in perturbative quantum chromodynamics. The measurement is used to validate new analysis techniques relevant for future measurements of τ lepton production. The measurement also provides the reconstruction efficiency and energy scale for τ decays to hadrons+ντ final states, determined with respective relative uncertainties of 2.2 and 0.9%.",
