Detailed Description

Class for Flatte resonance shape.

Author: Daniel Greenwald

Amplitude is 1 / (mass^2 - s - i * sum_channels(coupling * phase-space factor)

phase space factor := 2 * breakup-momentum / m; may be complex

Constructor & Destructor Documentation

Flatte ( double m = -1 )

inline

Constructor

Parameters

m	mass [GeV]

Member Function Documentation

virtual void calculateT	(	DataPartition &	D,
		const std::shared_ptr< ParticleCombination > &	pc,
		unsigned	si
	)		const

overrideprotectedvirtual

Calculate dynamic amplitude T for and store in each DataPoint in DataPartition

Parameters

D	DataPartition to calculate on
pc	ParticleCombination to calculate for
si	SymmetrizationIndec to calculate for

Implements MassShape.

virtual void checkDecayChannel ( const DecayChannel & c ) const

overridevirtual

Check if a DecayChannel is valid for this MassShape; will throw if invalid. Cheks that decay is to a channel of the Flatte
