Particlization in hybrid models

“…[13], the momentum distribution of each particle species is calculated by integrating over the particlization surface, Eq. ( 1), like in the conventional calculation of particle spectra in hydrodynamical models [41,42]. The number of particles of species i per unit rapidity, dN i /dy, in these boost-invariant distributions is calculated, and the sampling is constrained to produce either 10dN i /dy particles in a wide rapidity interval of −5 < y < 5 [41], or dN i /dy particles in an interval −0.5 < y < 0.5 [13].…”

“…These yields are not integers, however. In VISHNU the yield, 10dN i /dy, is rounded down to the nearest integer [41], whereas in ref. [13] the decimal part is taken as a probability whether to create one additional particle over the rounded down yield [42].…”
