$\pt$-differential production cross sections of prompt $\Dzero$, $\Dplus$, $\Dstar$, and $\Ds$ mesons at midrapidity ($|y|<0.5$) in pp collisions at $\s=13$ TeV The vertical bars and boxes report the statistical and systematic uncertainties, respectively. The total systematic uncertainties reported in the plots do not include the contributions of the luminosity and the branching ratio, which are reported separately. The measured prompt $\Dstar$-meson production cross section was scaled by a factor of $1/5$ for better visibility reasons.
