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

International audienceThe 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$^{∗±}$, D$^{±}$, and D$^{0} \left({\overline{\mathrm{D}}}^0\right) $ mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p$_{T}$< 100 GeV and |η| < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.[graphic not available: see fulltext
