Functions
std::vector< PdgId >	Hammer::flipSigns (const std::vector< PdgId > &list)
	return the PDG codes of the conjugate particles (itself if self-conjugate) for all the PDG codes in alist More...
PdgId	Hammer::flipSign (const PdgId &id)
	return the PDG code of the conjugate particle (itself if self-conjugate) More...
std::vector< PdgId >	Hammer::combineDaughters (const std::vector< PdgId > &daughters, const std::vector< PdgId > &subDaughters={})
	combine list of codes of daughters and grandaughters (for processes which parameterise two subsequent decays in a single amplitude) in a single list for computing hashes the convention is that daughters are ordered within themselves, grandDaughters are ordered within themselves, and then the two groups are concatenated with daughters first More...
HashId	Hammer::processID (PdgId parent, const std::vector< PdgId > &allDaughters)
	compute a unique ID for a given process based on the PDG codes of the parent particle and the ordered list of the daughters (and grandaughters if present) More...
HashId	Hammer::combineProcessIDs (const std::set< HashId > &allIds)
bool	Hammer::pdgSorter (PdgId a, PdgId b)
	sorting function for PDG ids for computing hashes. More...
bool	Hammer::particlesByPdg (const std::function< PdgId(const Particle &)> &pdgGetter, const Particle &a, const Particle &b)
	checks whether two particles are ordered according to the PDG code ordering used in computing hashes (see pdgSorter for more info on the ordering) More...
