标题： Charged hadron spectra and anisotropic flow from the AMPT model with shear viscous transport dynamics simulations at RHIC

摘要： 我们利用AMPT模型模拟了在200 GeV的Au+Au碰撞中，恒定比剪切粘度和不同相变温度下部分子物质的剪切粘性输运动力学。 所得的带电强子谱和各向异性流剖面与实验数据非常吻合。 横向动量谱和纵向去相关性基本上不受相变温度的影响。 相变温度的升高会导致中能区粒子产额增加，同时伴随椭圆流和三角流在一定范围的横向动量和赝快度上的下降。 显示英文摘要

摘要： We utilized the AMPT model to simulate the shear viscous transport dynamics of parton matter in Au+Au collisions at a constant specific shear viscosity and varying phase transition temperatures at 200 GeV. The resulting charged hadron spectra and anisotropic flow profiles correspond closely with experimental data. The transverse momentum spectra and longitudinal decorrelations are essentially unaffected by the phase transition temperature. An increase in the phase transition temperature leads to a rise in particle yields at midrapidity, accompanied by a decrease in both elliptic and triangular flows over a range of transverse momenta and pseudorapidities.
