Herwig 7.3.0
Interfaces defined for the Herwig::TwoPionRhoCurrent class.
Brief class description:
The TwoPionRhoCurrent class is designed to implement weakdecay to two scalar mesons using the models of either Kuhn and Santamaria (Z. Phys. C48, 445 (1990)) or Gounaris and Sakurai Phys. Rev. Lett. 21, 244 (1968). The mixing parameters are taken from Phys. Rev. D61:112002,2000 (CLEO), although the PDG values for the masses and widths are used, for the decay pi+/- pi0.
