Abstract

The transverse momentum (p(T)) differential yields of (anti-)He-3 and (anti-)H-3 measured in p-Pb collisions at √sNN = 5.02 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The ratios of the p(T)-integrated yields of (anti-)He-3 and (anti-)H-3 to the proton yields are reported, as well as the pT dependence of the coalescence parameters B-3 for (anti-)He-3 and (anti-)H-3. For (anti-)He-3, the results obtained in four classes of the mean charged-particle multiplicity density are also discussed. These results are compared to predictions from a canonical statistical hadronization model and coalescence approaches. An upper limit on the total yield of (4)(He) over bar is determined.
