Invariant differential yields of tritonsand $^{3}$He nuclei (left panel) and their antinuclei (right panel)in inelastic pp collisions at $\sqrt{s}$ = 7 TeV Error bars and boxes represent the statistical and systematic uncertainties,respectively, and the dashed line the result of a fit with a Tsallis function(see Sec. \ref{sub:yields-mean-pt} for details).
