The τ decay library TAUOLA, update with exact O (α) QED corrections in τ → μ(e) v v decay modes
Description
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). Versions of this program held in the CPC repository in Mendeley Data ABZP_v1_0; TAUOLA, version 1.5; 10.1016/0010-4655(91)90038-M ABZP_v2_0; TAUOLA, version: 2.1; 10.1016/0010-4655(92)90092-D ABZP_v3_0; TAUOLA, version: 2.4; 10.1016/0010-4655(93)90061-G This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
