Static Public Member Functions
static bool	isInSU2Doublet (tcPDPtr p)
	Return true, if the left-(right-)handed projection of this particle (antiparticle) belongs to a weak SU(2) doublet.
static bool	isSU2Up (tcPDPtr p)
	Return true, if the left-(right-)handed projection of this particle (antiparticle) is the up component of a weak SU(2) doublet.
static bool	isSU2Down (tcPDPtr p)
	Return true, if the left-(right-)handed projection of this particle (antiparticle) is the down component of a weak SU(2) doublet.
static tcPDPtr	SU2CC (tcPDPtr p, int familyShift=0)
	Return the conjugate component in the same weak SU(2) doublet, or a null pointer if the left-(right-)handed projection of this particle (antiparticle) does not belong to a weak SU(2) doublet.
static int	family (tcPDPtr p)
	Return the family.
