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