Theoretical Aspects of $τ\to K h (h) ν_τ$ Decays and Experimental Comparisons
Predictions for decay rates and distributions for $τ$ 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 $KKπ$ decay modes. For the $Kππ$ modes, disagreements with the experimental results can be traced back to the $K_1$ widths.
