The production of the charm-strange baryon is measured for the first time at the LHC via its semileptonic decay into e in pp collisions at TeV with the ALICE detector. The transverse momentum () differential cross section multiplied by the branching ratio is presented in the interval at mid-rapidity, . The transverse momentum dependence of the baryon production relative to the 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.
