摘要
We report the results of our improved calculation of the radiative corrections to the decay tau --> pi(K)nu(tau) which includes internal bremsstrahlung and structure dependent radiation in the radiative decay and point meson, hadronic structure dependent and short distance contributions in the virtual corrections. Our result for the radiative correction to the ratio GAMMA(tau --> pinu(tau)(gamma))/GAMMA(pi --> munu(mu)(gamma)) is deltaR(tau/pi) = (0.16(-0.14)+0.09)%. For the ratio GAMMA(tau --> Knu(tau)(gamma))/GAMMA(K --> munu(mu)(gamma)), we obtain delta(tau/K) = (0.90(-0.22)+0.04)%.
