Description

Production of strange mesons (KS) and baryons (Λ) have been studied with the LHCb in p-Pb collisions at √s = 5 TeV. Cross sections as well as their ratios (Λ-bar/KS, Λ-bar/Λ) have been measured differentially in transverse momentum between 0.15 and 7.0 GeV/c and rapidity in the ranges 1.5 < y < 4.0 and −5 < y < −2.5. The nuclear modification factors are measured for given transverse momentum and rapidity regions as well. Cross section spectra are compared with theoretical predictions in frame of Hybrid (Hydrodynamics, Coalescence, jett Fragmentation) and Parton-Hadron-String Dynamics (PHDS) models.
