Abstract

The inclusive production of the charm-strange baryon ωc0 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 center-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
