The Baryon1MesonDecayerBase
class is the base class for the decay of a baryon to another baryon and a pseudoscalar or vector meson.
All the matrix elements involving either a spin-1/2 or spin-3/2 baryons are now implemented apart from . The matrix elements are implemented in a general form with general couplings which must be supplied in classes inheriting from the one by implementing one of the coupling members.
