Abstract

Production of multi strange hadrons like cascade (Ξ) and omega(Ω) baryons are studied microscopically using rate equation at √s_NN=2.76 TeV, Large Hadron Collider(LHC) energy. The rate equations for Ξ, Ω are solved simultaneously with other strange hadrons in an expanding medium. The results for Ξ and Ω are compared with the data obtained from Pb-Pb collisions at √s_NN= 2.76 TeV from ALICE experiments. The ratio of yields of Ξ and Ω to π are analysed with various initial conditions and compared with the experimental observations made for various charge particle multiplicities.
