Description
Any measurement of a physical quantity in particle physics is a complicated process involving a Monte Carlo simulation of the detector response to a physical signal. With the accuracy sought nowadays, the relation between a theory and a measurement can be established at high precision only by providing the experimental groups with Monte Carlo event generators simulating the measured processes. I will give a short overview on the work undertaken by the Working Group on Radiative Corrections and MC Generators for Low Energies, that covers fours main areas: R measurement either with direct scan or with Initial State Radiation, Luminosiy and Tau. After that, I will focus on our contributions to the hadronic matrix elements for tau decays, that can improve this part of TAUOLA. Along the same lines, we plan to tackle the study of hadronic final states in e+e- annihilation, which may be of use for PHOKHARA.
