virtual ~LauKMatrixProdPole()
Destructor.
virtual LauComplex resAmp(Double_t mass, Double_t spinTerm)
Function not meant to be called, amplitude is called directly in this case.
virtual void initialise()
Initialise the model.
Class that defines the particular 3-body decay under study.
Definition: LauDaughters.hh:33
Int_t poleIndex_
The number of the pole.
virtual LauComplex amplitude(const LauKinematics *kinematics)
The amplitude calculation.
Class for defining a K-matrix production pole amplitude term.
LauKMatrixProdPole(const TString &poleName, Int_t poleIndex, Int_t resPairAmpInt, LauKMatrixPropagator *propagator, const LauDaughters *daughters)

Abstract class for defining type for resonance amplitude models (Breit-Wigner, Flatte etc...
File containing declaration of LauAbsResonance class.
Class for defining a complex number.
Definition: LauComplex.hh:47
LauKMatrixPropagator * thePropagator_
The K-matrix propagator.
Class for calculating 3-body kinematic quantities.
Class for defining a K-matrix propagator.
