Herwig 7.3.0
Interfaces defined for the Herwig::ThreePionDefaultCurrent class.
Brief class description:
The ThreePionDefaultCurrent class is designed to implement the three meson decays of the tau, ie pi- pi- pi+, pi0 pi0 pi-, K- pi- K+, K0 pi- Kbar0, K- pi0 K0,pi0 pi0 K-, K- pi- pi+, pi- Kbar0 pi0, pi- pi0 eta. It uses the same currents as those in TAUOLA.
