Interfaces defined for the Herwig::KPiKStarCurrent class.

Brief class description:

The KPiKStarCurrent 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. The decay K pi is assumed to be dominated by the lowest lying K* resonance.
