Abstract
The new data reported by ALICE on the production of light nuclei with in Pb-Pb collisions at are used to compute an order-of-magnitude estimate of the expected production cross sections of light nuclei in proton-proton collisions at high transverse momenta. We compare the hypertriton, helium-3, and deuteron production cross sections to that of , measured in prompt collisions by CMS. The results we find suggest a different production mechanism for the , making questionable any loosely bound molecule interpretation.
