论文摘要
我们建议将基于$ p_x $ - $ p_z $和$ p_y $ - $ p_z $ planes的角度分布的横向$ p_x $ - $ p_y $ plane的俗称流量分析扩展到新颖的流量系数。新的流量系数，称为$ u_n $和$ w_n $（除$ v_n $），还对核方程式也非常敏感，可以用来详细探索EOS，而不是仅使用$ v_n $的可能才能探索EOS。作为量化EOS效果的一个例子，使用了超偏好的量子分子动力学（URQMD）模型来研究E $ _ \ Mathrm {lab} = 1.23〜A $ GEV的20-30 \％Central Au+Au碰撞。
We propose to extend the commonly known flow analysis in the transverse $p_x$-$p_y$ plane to novel flow coefficients based on the angular distribution in the $p_x$-$p_z$ and $p_y$-$p_z$ planes. The new flow coefficients, called $u_n$ and $w_n$ (in addition to $v_n$), turn out to be also highly sensitive to the nuclear Equation-of-State and can be used to explore the EoS in more detail than is possible using only $v_n$. As an example to quantify the effect of the EoS, the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model is used to investigate 20-30\% central Au+Au collisions at E$_\mathrm{lab}=1.23~A$GeV.
