The neutrino emissivity from two- and three-flavor quark matter is numerically calculated and compared with Iwamoto’s formula. We find that the calculated emissivity is smaller than Iwamoto’s result by orders of magnitude when pf(u)+pf(e)−pf(d(s)) is comparable with the temperature. We attribute it to the severe restriction imposed by momentum conservation on the phase space integral. We obtain an alternative formula for the neutrino emissivity which is valid for any value of pf(u)+Pf(e)−Pf(d(s)) when the quarks and electrons are degenerate.

Phase Space Integral

The multiplicity distribution and the inelasticity coefficient are studied for proton–proton collisions at incident energies of 6, 19, 25, and 69 GeV. A theoretical model is proposed, based on a sequential decay system formed by the two interacting protons. The Monte Carlo technique is used to calculate the phase-space integral and for simulation of events for the different reactions.
