Member Function Documentation

double aTrial	(	const vector< double > &	invariants,
		const vector< double > &	masses
	)

overridevirtual

Evaluate the trial antenna given invariants and masses.

NOTE: for gluon emissions sab = sAB + + saj + sjb.

Implements ZetaGenerator.

void genInvariants	(	double	Q2In,
		double	zIn,
		double	sAnt,
		const vector< double > &	masses,
		vector< double > &	invariants,
		Logger *	loggerPtr,
		int	verboseIn
	)

overridevirtual

Set the invariants for the current value of the evolution variables.

Note: zeta = yjb = 1 implies saj = -sAB, so won't happen.

Implements ZetaGenerator.

double getzMin	(	double	Q2,
		double	sAnt,
		const vector< double > &	masses,
		double	xA = `1.`,
		double	xB = `1.`
	)

overridevirtual

Overridden methods.

ZGenIIEmitSoft. Everything written for the A-collinear side.

Overridden methods.

Implements ZetaGenerator.
