DESCRIPTION:Speakers: Pracheta Singha (Université de l'Ouest de Timișoar
 a\, Roumanie)\n\nThe interaction properties of the quark-gluon plasma (QGP
 )\, produced in relativistic heavy-ion collisions\, are governed by Quant
 um Chromodynamics (QCD). Low-energy effective models that reproduce the gl
 obal symmetry properties of QCD are particularly useful for exploring thi
 s strongly interacting matter in regions of phase space still inaccessible
  to first-principle lattice simulations. In this talk\, we focus on the Q
 CD phase structure at finite spin density using the linear sigma model co
 upled to quarks via a quark spin potential\, µΣ [1]. Spin polarization e
 ffects in the QGP have been experimentally observed in non-central heavy-i
 on collisions and are expected to influence the phase structure of the med
 ium. However\, lattice QCD simulations at finite µΣ remain significantly
  limited [2]. We will present the chiral phase diagram and thermodynamic p
 roperties of the medium at arbitrary temperature and spin density\, ensur
 ing consistency with lattice results through a proper vacuum renormalizati
 on procedure.References :1.⁠ ⁠P. Singha et al.\, “Chiral restoration
