The transverse momentum (pTâ) differential yields of (anti-)3He
and (anti-)3H measured in p-Pb collisions at sNNââ = 5.02 TeV
with ALICE at the Large Hadron Collider (LHC) are presented. The ratios of the
pTâ-integrated yields of (anti-)3He and (anti-)3H to the proton
yields are reported, as well as the pTâ dependence of the coalescence
parameters B3â 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 4HeË is determined.Comment: 30pages, 11 captioned figures, 4 tables, authors from page 25,
