THE TAU-DECAY LIBRARY TAUOLA, VERSION 2.4

The tau decay library TAUOLA has been enriched. The present version of the program includes more than twenty decay channels, including: (a) leptonic modes tau- --> nunueBAR- (gamma), nunumuBAR-(gamma), (b) one-meson modes: nupi-, nuK-, (c) two-meson modes: nupi- pi0(rho-), nuK0pi-(K*-), nuK- pi0(K*-), (d) three-meson modes: nupi- 2pi0(a1-), nu2pi- pi+(a1-), nuK+K- pi-, vK0K0piBAR-, nuK-k0pi0, nuK- pi0pi0, piK-pi-pi+, nuK0pi0pi-, nuetapi-pi0, (e) four-pion modes: nupi- 3pi0, nu2pi- pi+ pi0 (including the omegapi- contribution), (f) multi-pion modes: nunpi+/-,0 with n > 4, and finally the decay pi- --> nupi- pi0gamma from the omega --> pigamma. Complete O(alpha) QED corrections are included in the leptonic decay channels, and for other decay channels an interface is provided to the PHOTOS Monte Carlo generator for approximate simulation of the QED corrections. An interface to the tau pair production generators KORALB and KORALZ is also included. Final-state MC events are coded in the common block proposed by the Particle Data Group.
