Study of Bulk Properties of Strange Particles in Au+Au Collisions at (Formula presented.) GeV

We analyzed the transverse momentum (Formula presented.) spectra of various strange hadrons (Formula presented.), (Formula presented.) ((Formula presented.)) and (Formula presented.) ((Formula presented.)) at mid-rapidity (y) in different centrality intervals from Au+Au collisions at (Formula presented.) = 54.4 GeV. The (Formula presented.) spectra of these strange hadrons are investigated by the Tsallis-like distribution, which satisfactorily fits the experimental data. The bulk properties of the medium produced in ultra-relativistic heavy-ion collisions at the kinetic freeze-out are reflected by measuring the hadron spectra. The effective temperature T, transverse flow velocity (Formula presented.), and mean (Formula presented.) along with other parameters that are strongly dependent on centrality and particle specie are extracted. The effective temperature of multi-strange particle ((Formula presented.) ((Formula presented.))) is larger as compared to singly-strange particles (Formula presented.) ((Formula presented.)) and (Formula presented.). Furthermore, the kinetic freeze-out temperature T, transverse flow velocity (Formula presented.). and mean (Formula presented.) ((Formula presented.)) show a decreasing trend towards lower centrality, while the entropy parameter q increases from central to peripheral collisions. In addition, a positive correlation of (Formula presented.) and T and a negative correlation of q and T are also reported.
