The τ decay library TAUOLA, update with exact O (α) QED corrections in τ → μ(e) v v decay modes

Abstract
A new algorithm for the generation of the complete O (α) QED corrections for τ decays into leptons is presented. It provides an update to the τ decay library TAUOLA and can be easily combined with this library and any other bigger packages like KORALB or KORALZ which contain TAUOLA.

Title of program: TAUOLA, version: 2.1
Catalogue Id: ABZP_v2_0 [ACHG]

Nature of problem
Comparison with previous version, and reasons for new version: The powerful tau decay library is now available. This program, so far did not include QED radiative corrections in any of the decay modes. This update includes QED corrections for the decay modes tau -> mu(e)nu nu(bar).

摘要：本文提出了一种新的算法，用于生成τ衰变至轻子完整O(α)QED修正。该算法对τ衰变库TAUOLA进行了更新，并能轻松与TAUOLA库及任何包含TAUOLA的其他大型软件包，如KORALB或KORALZ相结合。

程序标题：TAUOLA，版本：2.1

目录编号：ABZP_v2_0 [ACHG]

问题性质：与先前版本相比，新版本的理由：强大的τ衰变库现已可用。该程序此前尚未包含任何衰变模式中的QED辐射修正。此次更新包含了τ → μ(e)νν̅衰变模式的QED修正。
