|V_us| from Strange Hadronic Tau Data
Elvira Gamiz, Matthias Jamin, Antonio Pich +2
We report on recent work to determine the CKM matrix element |V_{us}| using strange hadronic τdecay data. We use the recent OPAL update of the strange spectral function, while on t…
Towards a determination of the chiral couplings at NLO in 1/N(C): L_8(mu) and C_38(mu)
I. Rosell, J. J. Sanz-Cillero, A. Pich
We present a dispersive method which allows to investigate the low-energy couplings of chiral perturbation theory at the next-to-leading order (NLO) in the 1/N(C) expansion, keepin…
Theoretical overview on tau physics
Antonio Pich
Precise measurements of the tau lepton properties provide stringent tests of the Standard Model structure and accurate determinations of its parameters. We overview the present sta…
Spectral distribution for the decay tau -> nu_tau K pi
M. Jamin, A. Pich, J. Portoles
With the newly available data sets on hadronic tau decays from the B-factories BABAR and BELLE, and future data from BESIII, precise information on the decay distributions will soo…
Scalar K pi form factor and light quark masses
M. Jamin, J. A. Oller, A. Pich
Recent experimental improvements on K-decay data allow for a precise extraction of the strangeness-changing scalar K pi form factor and the related strange scalar spectral function…
