Description
Measurements of semileptonic B decays motivate searches for nonstandard charged-current interactions involving tau leptons. I will discuss a scalar–tensor scenario with right-chiral tau fields, connecting low-energy constraints to the mono-tau signature at the HL-LHC. The tau polarization is reflected in the charged–neutral pion energy sharing in tau decays, providing a possibility to distinguish this scenario from the Standard Model backgrounds. I will present preliminary results of an analysis of this observable, including event selection and background estimates, and discuss its potential to improve sensitivity to these interactions at high luminosity LHC.
