Constructor & Destructor Documentation

DecayType()

smash::DecayType::DecayType ( ParticleTypePtrList  part_types, int  l  )

inline

Construct a DecayType.

Parameters

[in]	part_types	Final-state particles of the decay.
[in]	l	Angular momentum of the decay.

Returns

The constructed object.

Definition at line 32 of file decaytype.h.

      : particle_types_(part_types), L_(l) {}

~DecayType()

virtual smash::DecayType::~DecayType ( )

virtualdefault

Virtual Destructor.

The declaration of the destructor is necessary to make it virtual.

Member Function Documentation

particle_number()

virtual unsigned int smash::DecayType::particle_number ( ) const

pure virtual

Returns

the number of particles in the final state

Implemented in smash::ThreeBodyDecay, and smash::TwoBodyDecay.

has_particles()

virtual bool smash::DecayType::has_particles ( ParticleTypePtrList  list ) const

pure virtual

Returns

if the final state consists of the given particle list.

Parameters

[in]

list

Final state particle types to be checked.

Implemented in smash::ThreeBodyDecay, and smash::TwoBodyDecay.

has_mother()

virtual bool smash::DecayType::has_mother ( [[maybe_unused] ] ParticleTypePtr  mother ) const

inlinevirtual

Returns

if this decay type has the right mother (most decays do not depend on the mother type).

Parameters

[in]

mother

Particle type to be checked.

                                                                         {
    return true;
  }

particle_types()

const ParticleTypePtrList& smash::DecayType::particle_types ( ) const

inline

Returns

the particle types associated with this branch.

Definition at line 58 of file decaytype.h.

{ return particle_types_; }

angular_momentum()

int smash::DecayType::angular_momentum ( ) const

inline

Returns

the angular momentum of this branch.

{ return L_; }

width()

virtual double smash::DecayType::width ( double  m0, double  G0, double  m  ) const

pure virtual

Returns

the mass-dependent width of the decay.

Parameters

[in]	m0	Pole mass of the decaying particle [GeV].
[in]	G0	Partial width at the pole mass [GeV].
[in]	m	Actual mass of the decaying particle [GeV].

Implemented in smash::ThreeBodyDecayDilepton, smash::ThreeBodyDecay, smash::TwoBodyDecayDilepton, smash::TwoBodyDecayUnstable, smash::TwoBodyDecaySemistable, and smash::TwoBodyDecayStable.

in_width()

virtual double smash::DecayType::in_width ( double  m0, double  G0, double  m, double  m1, double  m2  ) const

pure virtual

Returns

The mass-dependent in-width for a resonance formation process.

Parameters

[in]	m0	Pole mass of the produced resonance [GeV].
[in]	G0	Partial width at the pole mass [GeV].
[in]	m	Actual mass of the produced resonance [GeV].
[in]	m1	Actual mass of the first incoming particle [GeV].
[in]	m2	Actual mass of the second incoming particle [GeV].
