论文摘要
通过使用相对论性粘性因果流体动力学，研究了非零重型化学势和温度在非零重型化学势和温度下在超相关重型离子碰撞中产生的夸克和振动的热量火球的时空演变。为此，已经开发了数值代码来解决（3+1）维度中的相对论粘性因果流体动力学，并通过态度的方程和传输系数的缩放行为包括QCD临界点（CP）。我们已经评估了通过使用此代码来理解CP对这些可观察物的影响的横向动量光谱，定向和椭圆流系数。发现在整个火球的整个时空历史上的整合在很大程度上抑制了CP对光谱和流量系数的影响。
The space-time evolution of the hot and dense fireball of quarks and gluons produced in ultra-relativistic heavy-ion collisions at non-zero baryonic chemical potential and temperature has been studied by using relativistic viscous causal hydrodynamics. For this purpose a numerical code has been developed to solve the relativistic viscous causal hydrodynamics in (3+1)-dimensions with the inclusion of QCD critical point (CP) through the equation of state and scaling behaviour of the transport coefficients. We have evaluated the transverse momentum spectra, directed and elliptic flow coefficients of pions and protons to comprehend the effect of CP on these observables by using this code. It is found that the integration over the entire space-time history of the fireball largely obliterates the effects of CP on the spectra and flow coefficients.
