Performance of reconstruction and identification of τ leptons decaying to hadrons and <i>v</i><sub>τ</sub> in pp collisions at √<i>s</i>=13 TeV

The algorithm developed by the CMS Collaboration to reconstruct and identify $\tau$ leptons produced in proton-proton collisions at $\sqrt{s}=$ 7 and 8 TeV, via their decays to hadrons and a neutrino, has been significantly improved. The changes include a revised reconstruction of $\pi^0$ candidates, and improvements in multivariate discriminants to …
