摘要：

We present a new approach to radiative processes in e+e- annihilation based on a Monte Carlo method. This is nothing but the QED version of the parton shower model studied extensively in QCD. It is applicable to both initial and final state radiation but without the interference between these two. To examine the validity of the model, we compare it with the results of the exact calculations up to O(alpha) and O(alpha2). Comparison of several distributions shows that the model can give reliable results for practical use.
