Invariant differential yields of deuterons and antideuterons in

collisions at
√
s
= 0.9, 2.76 and 7 TeV and the yields of tritons,

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 (

reach of previous measurements up to 3 GeV/

nuclei exhibit an increasing trend with

and are found to be compatible with measurements in

collisions at low

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.
