The increase in yields of light nuclei with charged particle multiplicity, as reported by the ALICE collaboration at CERN p-p and p-Pb collisions LHC energy is investigated thermal hadron resonance gas model. model extended to account for exact baryon number conservation. focus on production protons, deuterons, $^3$He, $^3_\Lambda$H. A very good description proton deuteron obtained a function multiplicity mid-rapidity region using same fixed temperature central Pb-Pb collisions. $^3$He $^3_\Lambda$H though qualitatively explained are lower than expectation. One possible reasons could be that $^{3}$He $^{3}_{\Lambda}$H, chemical equilibrium not yet reached small multiplicities.
