The SU3BaryonDecupletOctetScalarDecayer
class is designed for the decay of a deculpet baryon to an octet baryon and a pseudoscalar meson from the lightest multiplet.
The coupling is taken to have the form
where is the decuplet field, is the octet field and is the pseudoscalar field, is the pion decay constant and is the coupling for the decay.
This is one of a number of decayers based on symmetry which are intended for the decay of excited baryons.
