Resumo: | The production of the charm-strange baryon Ξ0c is measured for the first time at the LHC via its semileptonic decay into e+ Ξ −νe in ppcollisions at √s=7TeV with the ALICE detector. The transverse momentum (pT) differential cross section multiplied by the branching ratio is presented in the interval 1 <pT<8GeV/cat mid-rapidity, |y| <0.5. The transverse momentum dependence of the Ξ 0c 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. |
