Anomalous Charged Current Couplings Of The Tau And Implications For Tau Compositeness And Two-Higgs Doublet Models, Maria-Teresa Dova, John Swain, Lucas Taylor

John Swain

The leptonic branching fractions of the tau lepton are sensitive to anomalous charged current interactions. We use recent experimental measurements to determine the weak charged current magnetic and electric dipole moments and the Michel parameter with unprecedented precision. These results are then used to constrain the tau compositeness scale and the allowed parameter space for Higgs doublet models.
