Description
The ALICE measurement of and production at midrapidity in Pb-Pb collisions at is presented. The transverse momentum () spectra are shown for several collision centrality intervals and in the range from ( for ) to . The dependence of the ratios exhibits maxima in the vicinity of , and the positions of the maxima shift towards higher with increasing collision centrality. The magnitude of these maxima increases by almost a factor of three between most peripheral and most central Pb-Pb collisions. This baryon excess at intermediate is not observed in interactions at and at . Qualitatively, the baryon enhancement in heavy-ion collisions is expected from radial flow. However, the measured spectra above progressively decouple from hydrodynamical-model calculations. For higher values of , models that incorporate the …
