static

Return the flavour content of the given particle.

The flavours will be given in decreasing mass with flavour before anti-flavour.

flavourContent() [3/5]

static vector<long> ThePEG::PDT::flavourContent ( tcPPtr  )

static

Return the flavour content of the given particle.

The flavours will be given in decreasing mass with flavour before anti-flavour.
