Sažetak (engleski)
Measurements of the production cross sections of prompt D0 , D+, D∗+, D+ s , Λ + c , and Ξ + c charm hadrons at midrapidity in proton-proton collisions at √ s = 13 TeV with the ALICE detector are presented. The D-meson cross sections as a function of transverse momentum (pT) are provided with improved precision and granularity. The ratios of pT-diferential meson production cross sections based on this publication and on measurements at diferent rapidity and collision energy provide a constraint on gluon parton distribution functions at low values of Bjorken-x (10−5–10−4 ). The measurements of Λ + c (Ξ + c ) baryon production extend the measured pT intervals down to pT = 0(3) GeV/c. These measurements are used to determine the charm-quark fragmentation fractions and the cc production cross section at midrapidity (|y| < 0.5) based on the sum of the cross sections of the weakly-decaying ground-state charm hadrons D0 , D+, D+ s , Λ + c , Ξ 0 c and, for the frst time, Ξ + c , and of the strongly-decaying J/ψ mesons. The frst measurements of Ξ + c and Σ 0,++ c fragmentation fractions at midrapidity are also reported. A signifcantly larger fraction of charm quarks hadronising to baryons is found compared to e +e − and ep collisions. The cc production cross section at midrapidity is found to be at the upper bound of state-of-the-art perturbative QCD calculations.
