Detailed Description

Class implementing a decay channel.

Author

Constructor & Destructor Documentation

DecayChannel

(

const ParticleVector &

daughters

)

N-particle Constructor (at the moment only valid for 2 particles). DecayChannel inherits ISP from daughters.

Parameters

daughters

Vector of shared_ptr's to daughter Particle's

Member Function Documentation

void addAllPossibleSpinAmplitudes

(

unsigned

two_J

)

automatically create all possible spin amplitudes given initial spin J

Parameters

two_J,(twice)

decaying particle's spin

void addSpinAmplitude

(

std::shared_ptr< SpinAmplitude >

sa

)

add a spin amplitude

Todo:

quantum numbers more completely?

const Model * model

(

)

const

Returns

raw pointer to model through first Daughter

const ParticleCombinationSet& particleCombinations ( ) const

inline

Returns

vector of ParticleCombinations

const PhaseSpaceFactorMap& phaseSpaceFactors ( ) const

inline

Returns

PhaseSpaceFactors_
