摘要：

We have calculated the O(alpha) radiative corrections to the tau decay tau --> pi(K)nu, taking into account both the point meson contribution and the structure dependent radiation, We find for the ratio GAMMA(tau --> pinu(gamma))/GAMMA(pi --> munu(gamma)) a radiative correction of +1.2% and for GAMMA(tau --> Knu(gamma))/GAMMA(K --> munu(gamma)) one of +2.0%. We compare our results with an earlier estimation and with experimental data.
