Measurement of prompt open-charm production cross sections in proton-proton collisions at $\sqrt{s}=$ 13 TeV

Abstract

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13 TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb${}^{-1}$. The differential production cross sections of the D${}^{\ast \pm }$, D${}^{\pm }$, and D${}^0$ (${\overline{\mathrm{D}}}^0$) mesons are presented in ranges of transverse momentum and pseudorapidity 4 $<$ $p_{\mathrm{T}}$ $<$ 100 GeV and $|\eta |$ $<$ 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.
