dc.description.abstract | Using 4.68 fb(-1) of e(+) e(-) annihilation data collected with the CLEO II detector at the Cornell Electron Storage Ring, we have studied tau radiative decays tau(-) --> nu(tau)mu(-)<<(nu)over bar>(mu)gamma and tau- --> nu(tau)e(-)<(nu)over bar>(e)gamma. For a 10 MeV minimum photon energy in the tau rest frame, the branching fraction for radiative tau decay to a muon or electron is measured to be (3.61 +/- 0.16 +/- 0.35) x 10(-3) or (1.75 +/- 0.06 +/- 0.17) x 10(-2), respectively. The branching fractions are in agreement with standard model theoretical predictions. | |
