Electromagnetic corrections in hadronic tau decay

Abstract
It is well known that in every experiment involving charged particles there are individual photons emitted with small energy /omega and those with /omega < /omega_{0} will not be detected but are present in the data. The typical procedure to estimate this effect consists in taking the leading logarithm from the soft photon approximation and to make a simulation through a Monte Carlo Algorithm (PHOTOS). The aim of this work is to compute the model independent QED correction to tau--> K /pi /nu and to estimate its effect in the decay width in the particular process tau^{+}-->K^{0} /pi^{+}/nu.
