The inclusive production of the charm-strange baryon Ω0c is measured for the first time via its semileptonic decay into Ω−e+νe at midrapidity (|y|<0.8) in proton−proton (pp) collisions at the centre-of-mass energy s√=13 TeV with the ALICE detector at the LHC. The transverse momentum (pT) differential cross section multiplied by the branching ratio is presented in the interval 2<12 GeV/c. The branching-fraction ratio BR(Ω0c→Ω−e+νe)/BR(Ω0c→Ω−π+) is measured to be 1.12 ± 0.22 (stat.) ± 0.27 (syst.). Comparisons with other experimental measurements, as well as with theoretical calculations, are presented.

Measurement of the Cross Sections of Ξ0c and Ξ+c Baryons and of the Branching-Fraction Ratio BR(Ξ0c→Ξ−e+νe)/BR(Ξ0c→Ξ−π+) in pp Collisions at √s = 13 TeV
ALICE Collaboration (American Physical Society, 2021)The pT-differential cross sections of prompt charm-strange baryons Ξ0c and Ξ+c were measured at midrapidity (|y|<0.5) in proton-proton (pp) collisions at a center-of-mass energy √s = 13 TeV with the ALICE detector at the ... -
Measurement of the fraction of jet longitudinal momentum carried by Λc+ baryons in pp collisions
ALICE Collaboration (American Physical Society (APS), 2024)Recent measurements of charm-baryon production in hadronic collisions have questioned the universality of charm-quark fragmentation across different collision systems. In this work the fragmentation of charm quarks into ... -
Measurement of the production cross section of prompt Ξ0c baryons at midrapidity in pp collisions at √s = 5.02 TeV
ALICE collaboration (Springer, 2021)The transverse momentum (pT) differential cross section of the charm-strange baryon Ξ0c is measured at midrapidity (|y| < 0.5) via its semileptonic decay into e+Ξ−νe in pp collisions at √s = 5.02 TeV with the ALICE detector ... -
Λc+ Production and Baryon-to-Meson Ratios in pp and p-Pb Collisions at √sNN = 5.02 TeV at the LHC
ALICE Collaboration (American Physical Society, 2021)The prompt production of the charm baryon Λ+c and the Λ+c/D0 production ratios were measured at midrapidity with the ALICE detector in pp and p-Pb collisions at √sNN = 5.02 TeV. These new measurements show a clear decrease ... -
Charm-quark fragmentation fractions and production cross section at midrapidity in pp collisions at the LHC
ALICE Collaboration (American Physical Society, 2022)Recent pT-integrated cross-section measurements of the ground-state charm mesons and baryons, D0, D+, Ds+, Λc+, and Ξc0, are used to evaluate the charm fragmentation fractions and production cross section per unit of ...
