  The new data reported by ALICE on the production of light nuclei with pT < 10
GeV in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV 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
X(3872), measured in prompt pp collisions by CMS. The results we find suggest a
different production mechanism for the X(3872), making questionable any loosely
bound molecule interpretation.
