Abstract
The decay spectra of τ - Ksπ- vτ and τ- K- ηVτ decays are studied in a combined analysis using a dispersive representation of the required vector and scalar form factors. The K*(1410) resonance parameters are extracted with improved precision as compared to previous studies, with the findings MK*' =1 304±17 MeV and ΓK*'=171±62 MeV. Isospin violations in the form factor slopes are investigated as the K- π0 vector form factor enters the description of the decay τ-K- ηvτ. In this respect, the spectrum of the transition τ K- π0vτwould be extremely useful.
