std::shared_ptr< DecayChannel > addChannel ( std::shared_ptr< DecayChannel > c )

overridevirtual

Add a DecayChannel to this Resonance

Parameters

c	unique_ptr to DecayChannel, should be constructed in function call, or use std::move(c)

Returns: shared_ptr to DecayChannel that has been added

Reimplemented from DecayingParticle.

void addParticleCombination ( const std::shared_ptr< ParticleCombination > & c )

overrideprotectedvirtual

add ParticleCombination to ParticleCombinations_, also add to MassShape_

Reimplemented from DecayingParticle.

void checkDecayChannel ( const DecayChannel & c ) const

overridevirtual

Check if a DecayChannel is valid for Resonance; will throw if invalid. checks with MassShape_
