چکیده
We investigated the strange hadrons transverse momentum (${p}_{T}$) spectra in Au-Au collision at $\sqrt{{s}_{NN}}=54.4\text{ }\text{ }\mathrm{GeV}$ framework of modified Hagedorn function with embedded flow. It is found that model can describe particle well. extracted kinetic freeze-out temperature ${T}_{0}$, flow velocity ${\ensuremath{\beta}}_{T}$, volume $V$, mean $⟨{p}_{T}⟩$, entropy parameter $n$, and multiplicity ${N}_{0}$. reported all these parameters increase towards central collisions. The larger temperature, velocity, volume, ($n$) collisions compared to peripheral show early decoupling particles In addition, above are mass dependent. (${T}_{0}$), ($⟨{p}_{T}⟩$) for massive particles, while (${\ensuremath{\beta}}_{T}$), ($V$), (${N}_{0}$) opposite behavior. Larger smaller ${\ensuremath{\beta}}_{T}$ as well $V$ heavier indicate $⟨{p}_{T}⟩$ evince effect radial stronger particles. separate set each shows multiple scenario, where mass-dependent differential scenario. also checked correlation among different parameters, which include ${T}_{0}$ $n$ they observed have positive correlations other validates our results.

Antilambda production in Au+Au collisions at 11.7A GeV/c.
We present results for antilambda and antiproton production in Au+Au collisions at 11.7 A GeV/c including spectra and extracted invariant yields for both species in central and peripheral collisions in the rapidity range 1.0<y<1.4. The antilambda yield increases from dN(Lambda;)/dy = 1.2(+0.7+0.2)(-0.6-0.2)x10(-3) in peripheral collisions to 19(+4+3)(-5-2)x10(-3) in central collisions. The dire...
متن کاملCollective expansion in central Au+Au collisions.
Energy spectra for intermediate mass fragments produced in central Au + Au collisions at E/A = 100 MeV indicate a collective expansion at breakup. For the first time, values for this collective expansion energy per nucleon are extracted independently for each charge. Typically, these values are one-third to one-half of the incident kinetic energy per nucleon in the c.m. system, but they decreas...
