The $\pt$ dependence of the $\bar{\mbox{p}}$/p ratio integrated over $|y| < 0.5$ for pp collisions at $\sqrt{s} = 0.9 $TeV (top) and $\sqrt{s} = 7 $TeV (bottom). Only statistical errors are shown for the data;the width of the Monte Carlo bands indicates the statistical uncertainty of the simulation results. |
