AI中文摘要：
我们在强子共振气体模型框架内分析了旋转对QCD物质手征交叉转变的影响。通过将重整化手征凝聚体的传统表述扩展到旋转强子介质，我们发现旋转显著改变了手征凝聚体，并随着角速度的增加系统地抑制了赝临界温度。我们研究了T-ω平面中的赝临界线，并通过领头阶和次领头阶旋转曲率系数量化了赝临界温度的旋转依赖性。我们进一步研究了角速度和重子化学势的联合效应，发现它们的相互作用导致赝临界温度的更强抑制。此外，通过赝临界温度的径向变化，我们考察了手征交叉转变的空间依赖性。我们发现赝临界温度随径向距离的增加而降低，表明随着远离旋转轴，手征交叉在逐渐更低的温度下发生。
英文摘要：
We analyze the impact of rotation on the chiral crossover transition of QCD matter within the framework of a hadron resonance gas model. By extending the conventional formulation of the renormalized chiral condensate to a rotating hadronic medium, we find that rotation significantly modifies the chiral condensate and systematically suppresses the pseudocritical temperature as the angular velocity increases. The pseudocritical line in the $T-ω$ plane is examined, and the rotational dependence of the pseudocritical temperature is quantified through leading- and next-to-leading-order rotational curvature coefficients. We further investigate the combined effects of angular velocity and baryon chemical potential and find that their interplay leads to a stronger suppression of the pseudocritical temperature. Additionally, the spatial dependence of the chiral crossover transition is examined through the radial variation of the pseudocritical temperature. We find that the pseudocritical temperature decreases with increasing radial distance, indicating that the chiral crossover sets in at progressively lower temperatures as one goes away from the rotation axis.
