Abstract
Results on the production of 4He and nuclei in Pb–Pb collisions at in the rapidity range |y|<1 , using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0–10% central events are found to be ... and ..., respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (Tchem = 156 MeV) as for light hadrons. The measured ratio of anti-He4/He4 is 1.4 +- 0.8 (stat) +- 0.5 (syst).File in questo prodotto:
