论文摘要
为了发现QCD临界点,至关重要的是开发可以嵌入重型离子碰撞模拟中的净 - 巴里昂数字波动的动态模型。在此程序中,我们研究了QCD临界点附近净 - 巴里昂数字的临界数量的动态形成及其在扩展系统中晚期的生存。具有非线性自由能函数的随机扩散方程用于描述QCD临界点附近的跨界和一阶过渡区域中的轨迹沿轨迹沿轨迹沿轨迹的演变。
For the discovery of the QCD critical point it is crucial to develop dynamical models of the fluctuations of the net-baryon number that can be embedded in simulations of heavy-ion collisions. In this proceeding, we study the dynamical formation of the critical fluctuations of the net-baryon number near the QCD critical point and their survival in the late stages in an expanding system. The stochastic diffusion equation with a non-linear free energy functional is employed for describing the evolution of conserved-charge fluctuations along trajectories in the crossover and first-order transition regions near the QCD critical point.
