Study of Bulk Properties of Strange Particles in Au+Au Collisions at [Formula: see text] = 54.4 GeV
We analyzed the transverse momentum [Formula: see text] spectra of various strange hadrons [Formula: see text] , [Formula: see text] ([Formula: see text]) and [Formula: see text] ([Formula: see text]) at mid-rapidity (y) in different centrality intervals from Au+Au collisions at [Formula: see text]...

description | We analyzed the transverse momentum [Formula: see text] spectra of various strange hadrons [Formula: see text] , [Formula: see text] ([Formula: see text]) and [Formula: see text] ([Formula: see text]) at mid-rapidity (y) in different centrality intervals from Au+Au collisions at [Formula: see text] = 54.4 GeV. The [Formula: see text] 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: see text] , and mean [Formula: see text] along with other parameters that are strongly dependent on centrality and particle specie are extracted. The effective temperature of multi-strange particle ([Formula: see text] ([Formula: see text])) is larger as compared to singly-strange particles [Formula: see text] ([Formula: see text]) and [Formula: see text]. Furthermore, the kinetic freeze-out temperature T, transverse flow velocity [Formula: see text]. and mean [Formula: see text] ([Formula: see text]) 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: see text] and T and a negative correlation of q and T are also reported. |
