Abstract
Strange quark production in relativistic heavy-ion collisions is used as a diagnostic tool as well as a signature for QGP formation. Strong interactions in the QGP medium generate strange quarks and antiquarks which don’t exist in normal matter. The reason being shortly after their production, they undergo decay via weak interactions. Its unique mass which is expected close to the temperature at which protons, neutrons and other hadrons turn into quarks. Hence, these strange quarks, antiquarks are sensitive to the conditions, structure and dynamics of the deconfined state of matter. It can be said that the deconfined state is reached if there is an abundance of strange quarks. In this proceedings we are going to discuss about the different hyperon yields (\(\Lambda , \Xi , \Omega \)) calculated using AMPT and UrQMD model.
