Measurement of the production cross section of prompt Xi(0)(c) baryons at midrapidity in pp collisions at root s=5.02 TeV
Original language description
The transverse momentum (p(T)) differential cross section of the charm-strange baryon Xi(0)(c) is measured at midrapidity (vertical bar y vertical bar < 0.5) via its semileptonic decay into e(+)Xi(-)nu(e) in pp collisions at root s = 5.02TeV with the ALICE detector at the LHC. The ratio of the p(T)-differential Xi(0)(c)-baryon and D-0-meson production cross sections is also reported. The measurements are compared with simulations with different tunes of the PYTHIA 8 event generator, with predictions from a statistical hadronisation model (SHM) with a largely augmented set of charm-baryon states beyond the current lists of the Particle Data Group, and with models including hadronisation via quark coalescence. The pT-integrated cross section of prompt Xi(0)(c)-baryon production at midrapidity is also reported, which is used to calculate the baryon-to-meson ratio Xi(0)(c)/D-0 = 0.20 +/- 0.04 (stat.)(-0.07)(+0.08) (syst.). These results provide an additional indication of a modification of the charm fragmentation from e(+) e(-) and e-p collisions to pp collisions.
