Invariant differential yield of deuterons(left panel) and antideuterons (right panel) in inelastic pp collisions (INEL)at $\sqrt{s}$ = 0.9, 2.76, and 7 TeV. Systematic uncertainties are representedby boxes and the data are multiplied by constant factors for clarity in the figure The lowest $p_{\text{T}}$ point for deuterons at $\sqrt{s}$ = 7 TeV was takenfrom . The dashed line represents the result of a fitwith a Tsallis function (see Sec. \ref{sub:yields-mean-pt} for details).
