Model-dependent radiative corrections to tau- -> pi- pi0 nu revisited
arXiv:hep-ph/0611226 · doi:10.1016/j.nuclphysbps.2007.03.011
Abstract
The long-distance electromagnetic radiative corrections to tau- -> pi- pi0 nu are re-evaluated. A meson dominance model is used to describe the emission of real photons in this decay. Results obtained for the hadronic spectrum and the decay rate in photon inclusive reactions are compared with previous calculations based on the chiral resonance theory. Independent tests in tau -> pi pi nu gamma that can help to validate the predictions of one of the two models are briefly discussed.
