Correlation studies on particle kinematics to improve mass reconstruction in single top quark associated H boson production (tHq) in the H →ττ channel at ATLAS — •Mathias Weiß, Tanja Holm, and Ian Brock for the ATLAS collaboration — Universität Bonn

The associated production of a top quark and a H boson (called tHq) allows experimental tests of the relative phase between g_HWW and y_t, the coupling constants of the H boson to the W boson and to the top quark.

In the decay channel H →ττ and t→ l with one hadronic τ and two light leptons, l, in the final state, missing neutrinos are the main challenge to mass reconstruction. This talk approaches this challenge by exploiting correlations derived from Monte Carlo samples with truth information, which simulate events taken by the ATLAS detector during Run 2 of the LHC.
