Abstract
The transverse momentum (p T ) differential yields of (anti-) 3 He and (anti-) 3 H measured in p-Pb collisions at s NN = 5.02 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The ratios of the p Tintegrated yields of (anti-) 3 He and (anti-) 3 H to the proton yields are reported, as well as the p T dependence of the coalescence parameters B 3 for (anti-) 3 He and (anti-) 3 H. For (anti-) 3 He, 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 is determined.
