The production of the charm-strange baryon Ξ c 0 is measured for the first time at the LHC via its semileptonic decay into eΞ−+ν e in pp collisions at s=7 TeV with the ALICE detector. The transverse momentum (p T ) differential cross section multiplied by the branching ratio is presented in the interval 1<p T <8 GeV/c at mid-rapidity, |y|<0.5. The transverse momentum dependence of the Ξ c 0 baryon production relative to the D 0 meson production is compared to predictions of event generators with various tunes of the hadronisation mechanism, which are found to underestimate the measured cross-section ratio.

Abstract
The production of the charm-strange baryon Ξ c 0 is measured for the first time at the LHC via its semileptonic decay into eΞ−+ν e in pp collisions at s=7 TeV with the ALICE detector. The transverse momentum (p T ) differential cross section multiplied by the branching ratio is presented in the interval 1
