dc.description.abstractInvariant differential yields of deuterons and antideuterons in p p collisions at √ s = 0.9, 2.76 and 7 TeV and the yields of tritons, 3 He nuclei, and their antinuclei at √ s = 7 TeV have been measured with the ALICE detector at the CERN Large Hadron Collider. The measurements cover a wide transverse momentum ( p T ) range in the rapidity interval | y | < 0.5 , extending both the energy and the p T reach of previous measurements up to 3 GeV/ c for A = 2 and 6 GeV/ c for A = 3 . The coalescence parameters of (anti)deuterons and 3 ¯¯¯¯ He nuclei exhibit an increasing trend with p T and are found to be compatible with measurements in p A collisions at low p T and lower energies. The integrated yields decrease by a factor of about 1000 for each increase of the mass number with one (anti)nucleon. Furthermore, the deuteron-to-proton ratio is reported as a function of the average charged particle multiplicity at different center-of-mass energies.
