Abstract

The production of the charm-strange baryon Ξ<inf>c</inf> ⁰ is measured for the first time at the LHC via its semileptonic decay into eΞ−+ν<inf>e</inf> in pp collisions at s=7 TeV with the ALICE detector. The transverse momentum (p<inf>T</inf>) differential cross section multiplied by the branching ratio is presented in the interval 1<p<inf>T</inf><8 GeV/c at mid-rapidity, |y|<0.5. The transverse momentum dependence of the Ξ<inf>c</inf> ⁰ baryon production relative to the D⁰ 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.
