Improved reconstruction of highly boosted τ-lepton pairs in the ττ(μνμντ)(hadrons+ντ) decay channels with the ATLAS detector / ATLAS Collaboration
This paper presents a new τ-lepton reconstruction and identification procedure at the ATLAS detector at the Large Hadron Collider, which leads to significantly improved performance in the case of physics processes where a highly boosted pair of τ-leptons is produced and one τ-lepton decays into a muon and two neutrinos (τμ), and the other decays into hadrons and one neutrino (τhad).
