Article: Radiative tau decay into pion[Show abstract] [Hide abstract]
ABSTRACT: The possibility of the experimental investigation of the radiative tau decay into pion is discussed including background conditions. The decay width is estimated to be Br(v )=0.15% (at the minimal registered photon energy 50 MeV). The contribution of the structural component is 10% of the total radiation. The main background is produced by photons from the v – 0 decay. We investigate the angular and energy spectra of the decay products and analyse the background conditions. The kinematic region was found where the structural radiation dominates over background.Zeitschrift für Physik C 02/1991; 50(1):113-121.
