Measurement of the Z/gamma* -> tau tau cross section in pp collisions at root s=13 TeV and validation of tau lepton analysis techniques
A measurement is presented of the Z/γ ∗ → τ τ cross section in pp collisions at √s = 13 TeV, using data recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 2.3 fb−1. The product of the inclusive cross section and branching fraction is measured to be σ (pp → Z/γ...

description |
A measurement is presented of the Z/γ ∗ → τ τ
cross section in pp collisions at √s = 13 TeV, using data
recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 2.3 fb−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% |
