Uses the TDatabasePDG class, which is filled from evt.pdl by basf2.

Function Documentation

antiParticleListName()

std::string antiParticleListName	(	int	pdgCode,
		const std::string &	label
	)

Returns the name of the anti-particle ParticleList for particles with given pdg code and with given label.

If the anti-particle does not exist the particle's name is returned instead

Definition at line 30 of file EvtPDLUtil.cc.

{
  if (label.empty())
    return antiParticleName(pdgCode);
  return antiParticleName(pdgCode) + ":" + label;
}

antiParticleName()

std::string antiParticleName

(

int

pdgCode

)

Returns the name of the anti-particle of a particle with given pdg code.

If the anti-particle does not exist the particle's name is returned instead.

hasAntiParticle()

bool hasAntiParticle

(

int

pdgCode

)

Checks if the particle with given pdg code has an anti-particle or not.

Parameters

pdgCode

of the particle

Returns

true/false if anti-particle does/does not exist
