Abstract

The production of the charm-strange baryon Ξ0c is measured for the first time at the LHC via its semileptonic decay into eΞ−+νe in pp collisions at √s=7 TeV with the ALICE detector. The transverse momentum (pT) differential cross section multiplied by the branching ratio is presented in the interval 1<pT<8 GeV/c at mid-rapidity, |y|<0.5. The transverse momentum dependence of the Ξ0c predictions of event generators with various tunes of the hadronisation mechanism, which are found to underestimate the measured cross-section ratio.
