The pt-differential inclusive production cross sections of the prompt charmed mesons D0, D+, and D∗+ in the rapidity range |y| <0.5 were measured in proton-proton collisions at √s = 7 TeV at the LHC using the ALICE detector. Reconstructing the decays D0 → K−π+, D+ → K−π+π+, D∗+ → D0π+, and their charge conjugates, about 8,400 D0, 2,900 D+, and 2,600 D∗+ mesons with 1 <pt <24 GeV/c were counted, after selection cuts, in a data sample of 3.14×108 events collected with a minimum-bias trigger (integrated luminosity Lint = 5 nb−1). The results are described within uncertainties by predictions based on perturbative QCD.

Theoretical predictions for charm and bottom production at the LHC (2012, unknown): “[52] are also compared to the theoretical prediction, showing a good agreement within the large systematics.”
Extraction of heavy-flavor transport coefficients in QCD matter (2018, background): “76 TeV, because the available D-meson cross section measurements at this energy at central rapidity [19] have much larger experimental uncertainties than the data at the higher energies.”
Measurement of D-meson production at mid-rapidity in pp collisions at √s=7 TeV (2017, background): “76 TeV [15] and with the measurements of the LHCb collaboration at forward rapidity (2.”
Prompt charm production in pp collisions at sqrt(s)=7 TeV (2013, background): “Charm production at the LHC in pp collisions at √ s = 7 TeV is studied with the σ(cc)pT 8GeV/c, 2.0 y 4.5 = 1419± 12 (stat)± 116 (syst)± 65 (frag)µb, where the uncertainties are statistical, systematic, and due to the fragmentation functions.”
Λ c + production in pp collisions at √s=7 TeV and in p-Pb collisions at √sNN=5.02 TeV (2017, methodology): “This corresponds to the “maximum probability” strategy discussed in [58] that was, for example, successfully validated in reproducing the published results [60] for the D 0 → K − π + production cross section, which were obtained with a PID strategy based on a | n σ | 3 selection.”
Heavy-flavour and quarkonium production in the LHC era: from proton–proton to heavy-ion collisions (2015, unknown): “In the STAR experiment, quarkonia are reconstructed at mid-rapidity (|y| 1) thanks to the electron identification and momentum measurements from the TPC.”
