Production of light antinuclei in heavy ion collisions

Abstract

The antideuteron and antihelium-3 production rates at high-energy heavy ion collisions are calculated in the framework of fusion mechanism. It is supposed, that anti-p,n,d,^3He participating in the fusion are moving in the mean field of other fireball constituents. It is demonstrated that at high energies, where many pions are present in the fireball, the number of produced anti-d and ^3He is determined by the balance between created and desintegrated (mainly in collisions with pions) anti-d and ^3He. The explicit formulae for coalescence parameters are presented and compared with the data.
