Combined analysis of the decays τ−→ KSπ−ντ and τ−→ K−ηντ

Abstract In a combined study of the decay spectra of τ−− KSπ−ντ and τ−− K−ηντ decays within a dispersive representation of the required form factors, we illustrate how the K*(1410) resonance parameters, defined through the pole position in the complex plane, can be extracted with improved precision...

520			\|a Abstract In a combined study of the decay spectra of τ−− KSπ−ντ and τ−− K−ηντ decays within a dispersive representation of the required form factors, we illustrate how the K(1410) resonance parameters, defined through the pole position in the complex plane, can be extracted with improved precision as compared to previous studies. While we obtain a substantial improvement in the mass, the uncertainty in the width is only slightly reduced, with the findings MK′ = 1304 ± 17 MeV and $ Γ_{K*′} $ = 171 ± 62 MeV. Further constraints on the width could result from updated analyses of the Kπ and/or Kη spectra using the full Belle-I data sample. Prospects for Belle-II are also discussed. As the K−π0 vector form factor enters the description of the decay τ−− K−ηντ, we are in a position to investigate isospin violations in its parameters like the form factor slopes. In this respect also making available the spectrum of the transition τ−→ K−π0ντ would be extremely useful, as it would allow to study those isospin violations with much higher precision.

While we obtain a substantial improvement in the mass, the uncertainty in the width is only slightly reduced, with the findings MK′ = 1304 ± 17 MeV and $ Γ_{K*′} $ = 171 ± 62 MeV. Further constraints on the width could result from updated analyses of the Kπ and/or Kη spectra using the full Belle-I data sample. Prospects for Belle-II are also discussed. As the K−π0 vector form factor enters the description of the decay τ−− K−ηντ, we are in a position to investigate isospin violations in its parameters like the form factor slopes. In this respect also making available the spectrum of the transition τ−→ K−π0ντ would be extremely useful, as it would allow to study those isospin violations with much higher precision.

title_auth	Combined analysis of the decays τ−→ KSπ−ντ and τ−→ K−ηντ
abstract	Abstract In a combined study of the decay spectra of τ−− KSπ−ντ and τ−− K−ηντ decays within a dispersive representation of the required form factors, we illustrate how the K(1410) resonance parameters, defined through the pole position in the complex plane, can be extracted with improved precision as compared to previous studies. While we obtain a substantial improvement in the mass, the uncertainty in the width is only slightly reduced, with the findings MK′ = 1304 ± 17 MeV and $ Γ_{K*′} $ = 171 ± 62 MeV. Further constraints on the width could result from updated analyses of the Kπ and/or Kη spectra using the full Belle-I data sample. Prospects for Belle-II are also discussed. As the K−π0 vector form factor enters the description of the decay τ−− K−ηντ, we are in a position to investigate isospin violations in its parameters like the form factor slopes. In this respect also making available the spectrum of the transition τ−→ K−π0ντ would be extremely useful, as it would allow to study those isospin violations with much higher precision. © The Author(s) 2014
