The inclusive production of the charm-strange baryon Ω0 c is measured for the first time via its semileptonic decay into Ω−eþνe at midrapidity (jyj < 0.8) in proton-proton (pp) collisions at the center-ofmass energy ffiffi s p ¼ 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 < pT < 12 GeV=c. The branching-fraction ratio BRðΩ0 c → Ω−eþνeÞ=BRðΩ0 c → Ω−πþÞ 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.
