Theoretical Aspects of $\tau \to K h (h) \nu_\tau$ Decays and Experimental Comparisons

Abstract

Predictions for decay rates and distributions for $\tau$ decays into final states with kaons are discussed and compared with recent measurements. Special emphasis is put on new constraints for the vector current contribution in the $KK\pi$ decay modes. For the $K\pi\pi$ modes, disagreements with the experimental results can be traced back to the $K_1$ widths.
