Description
$\Omega$($\bar{\Omega}$), composed of three strange quarks, serves as a sensitive probe into the characteristics of the quark-gluon plasma (QGP). Measurement of its production can be used to extract the temperature and baryon chemical potential at the chemical freeze-out with the statistical hadronization model, providing information on the QCD phase diagram. Also, the $\Omega$/$\phi$ ratio as a function of transverse momentum ($p_T$) can be utilized to test hadronization model predictions and to possibly extract the strange quark $p_T$ distribution at hadronization.
In this poster, we will present $p_T$ spectra and yields of $\Omega$($\bar{\Omega}$) in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The data analyzed were collected by STAR in 2019, when the iTPC was in operation. The iTPC extends the rapidity coverage and enhances the particle identification capability compared to previous results.
