Cascade and Omega productions from Pb+Pb Collisions at LHC energy

Abstract

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