Abstract

The production of the charm-strange baryon Csi-0 is measured for the first time at the LHC via its semileptonic decay into e+ Csi- 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 Csi-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.
