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 303 of file RandomGenerators.h.

Constructor & Destructor Documentation

◆ BoostInvariantMomentumGenerator()

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 )

Construct a new BoostInvariantMomentumGenerator object.

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

Definition at line 283 of file RandomGenerators.cpp.

◆ ~BoostInvariantMomentumGenerator()

thermalfist::RandomGenerators::BoostInvariantMomentumGenerator::~BoostInvariantMomentumGenerator ( )

virtual

BoostInvariantMomentumGenerator desctructor.

Will free the memory used by the object pointed to by m_FreezeoutModel

Member Function Documentation

◆ EtaMax()

double thermalfist::RandomGenerators::BoostInvariantMomentumGenerator::EtaMax ( ) const

inline

Definition at line 327 of file RandomGenerators.h.

◆ GetMomentum()

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, and, additionally, the space-time Cartesian coordinates \(r_0\), \(r_x\), \(r_y\), \(r_z\) in the collision center-of-mass frame

Implements thermalfist::RandomGenerators::ParticleMomentumGenerator.

◆ GetRandomZeta()

double thermalfist::RandomGenerators::BoostInvariantMomentumGenerator::GetRandomZeta ( MTRand & rangen = RandomGenerators::randgenMT ) const

protectedvirtual

Samples zeta for use in Monte Carlo event generator.

Uses rejection sampling.
