Effects of anomalous charged current dipole moments of the tau on the decay $τ^-\toν_τπ^-π^0$

We analyse the process $τ^-\toν_τπ^-π^0$ allowing for anomalous weak charged current magnetic and electric dipole moment interactions and determine the effects on the differential and total decay rates. Using recent experimental data we determine the following values for the anomalous magnetic and electric dipole moment parameters, respectively: $κ= 0.16 \pm 0.08; and |\tildeκ| = 0.88^{+0.25}_{-0.35}.$

Anomalous charged current couplings of the tau and implications for tau compositeness and two-Higgs doublet models

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 $η$ with unprecedented precision. These results are then used to constrain the tau compositeness scale and the allowed parameter space for Higgs doublet models.
