generateBiased()

void G4INCL::PhaseSpaceGenerator::generateBiased	(	const G4double	sqrtS,
		ParticleList &	particles,
		const size_t	index,
		const G4double	slope
	)

Generate a biased event in the CM system.

This method first generates a "flat" event by calling generate(). The particles are subsequently rotated in such a way that one of them (identified by the parameter index) is biased towards the collisionAxis with an exponential distribution of the form

where is the usual Mandelstam variable. The incoming momentum is taken to be the momentum of particles[index] at the moment of the call.

Parameters

sqrtS	total energy in the centre of mass, in MeV
particles	list of particles for which the event will be generated (modified on exit)
index	index of the particle to be biased; all the other particles will follow
slope	slope of the angular distribution: , in (GeV/c)^(-2)
