Abstract The τ decay library TAUOLA has been enriched. The present version of the program includes more than twenty decay channels, including: (a) leptonic modes τ^-→ nνe^-→ nνμ^- (γ), (b) one-meson modes: νπ^- , νK^- , (c) t wo-meson modes: νπ^-π^0 (ρ{variant}^- ), νK^0 π^-(K^(*-)), νK^-π^0 (K^(*-)), (d) three-meson modes: νπ^- 2ν ^0 (a^- _1 ), ν2π^- π^+(a^- _1 ), νK^+K^-π^- , ν K̄^0 K^0 π^- , νK^-K̄^0 π^0 , νK^-π^0 π^0 , νK^-π^- π^+ , νK^0 π^0 π^- , νηπ^- π ^0 , (e) four-pi... Title of program: TAUOLA, version: 2.4 Catalogue Id: ABZP_v3_0 [ACNS] Nature of problem Comparison with the previous version, and reasons for the new version The tau decay library [2] is enriched by new decay modes involving kaons: tau- ->nuK+K-pi-, nuKbar^0K^0pi-, nuK-K^0pi^0, nuK-pi^0pi0, nuK-pi-pi+, nuK^0pi^0pi-, etanupi-pi^0, the omega pi contribution to nupi-pi0gamma. For the tau decay modes into four pions tau- ->nu2pi-pi+pi0, pi-3pi0, the simplified dynamical treatment has been replaced by a more appropriate one, in particular, the omegapi contribution and rho enhanc ...
