The transverse momentum (pT) differential yields of (anti-)He3 and (anti-)H3 measured in p-Pb collisions at sNN = 5.02 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The ratios of the pT-integrated yields of (anti-)He3 and (anti-)H3 to the proton yields are reported, as well as the pT dependence of the coalescence parameters B3 for (anti-)He3 and (anti-)H3. For (anti-)He3, 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 4Hē is determined.
