GetMomentum()

std::vector< double > thermalfist::RandomGenerators::SSHMomentumGenerator::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
