Description:
Author(s): R. Escribano, S. Gonzàlez-Solís, and P. Roig We analyze the second-class current decays τ − → π − η ( ′ ) ν τ in the framework of chiral perturbation theory with resonances. Taking into account π 0 − η − η ′ mixing, the π − η ( ′ ) vector form factor is extracted, in a model-independent way, using existing data on the π − π 0 one. For the participant scalar form fact… [Phys. Rev. D 94, 034008] Published Fri Aug 05, 2016
