Detailed Description

Class for generating momentum of a particle in accordance with a longitudinally boost invariant and azimuthally symmetric freeze-out model.

Definition at line 294 of file RandomGenerators.h.

Constructor & Destructor Documentation

thermalfist::RandomGenerators::BoostInvariantMomentumGenerator::BoostInvariantMomentumGenerator	(	BoostInvariantFreezeoutParametrization *	FreezeoutModel = `NULL`,
		double	Tkin = `0.100`,
		double	etamax = `3.0`,
		double	mass = `0.938`,
		int	statistics = `0`,
		double	mu = `0`
	)

Parameters

FreezeoutModel	Pointer to a BoostInvariantFreezeoutParametrization object. Will be deleted on destruction!
Tkin	The kinetic temperature (in GeV)
etamax	The longitudinal space-time rapidity cut-off
mass	Particle mass (in GeV)
statistics	Quantum statistics (default: Maxwell-Boltzmann)
mu	Chemical potential (in GeV). Only matters for quantum statistics

std::vector< double > thermalfist::RandomGenerators::BoostInvariantMomentumGenerator::GetMomentum ( double mass = -1. ) const

virtual

Samples the 3-momentum of a particle

Parameters

mass	The mass of a particle. If negative value provided, defaults to the pole/vacuum mass

Returns: std::vector<double> A vector containing the sampled \(p_x\), \(p_y\), \(p_z\) components of the three-momentum
