Production of (anti-)He3 and (anti-)H3 in p-Pb collisions at sNN=5.02 TeV

The transverse momentum (pT) differential yields of (anti-)3He and (anti-)3H measured in p–Pb collisions at √ sNN = 5.02 TeV with ALICE at the LHC are presented. The ratios of the pT-integrated yields of (anti-)3He and (anti-)3H to the proton yields are reported, as well as the pT dependence of the coalescence parameters B3 for (anti-)3He and (anti-)3H. For (anti-)3He, 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 4He is determined.
