$\pt$-differential inclusive cross section for prompt $\Dzero$, $\Dplus$, and$\Dstar$ mesons in pp collisions at $\sqrts=7 $TeV compared with FONLL and GM-VFNS  theoretical predictions. The symbols are positionedhorizontally at the centre of each $\pt$ interval. The normalization uncertainty is not shown (3.5\% from the minimum-bias cross section plus the branching ratio uncertainties, as of Table 2).
