论文摘要
各向异性流量系数，$ v_n $，非线性流量模式系数，$χ_{n，mk} $以及不同的对称平面之间的相关性，$ρ_{n，mk} $在$ \ sqrt {s_s_ s_ \ rm rm rm rm rm rm rm rm {nn n n n n n n n in pb-pb碰撞中测量。报告了横向动量间隔$ 0.2 <p_ \ rm {t} <5.0 $ gev/$ c $在pseudorapition Interval $ 0.4 <|η| <0.8 $的结果作为横向动量间隔$ 0.2 <p_ \ rm {t} <5.0 $ gev/$ c $。 $ v_n $系数和$χ_{n，mk} $和$ρ_{n，mk} $分别显示为第九和第七次谐波顺序。计算表明，在不同的对称平面和非线性流量模式系数中测量的相关性取决于重型离子碰撞中产生的培养基的剪切和散装粘度与熵比。这些测量值与较低能量的测量值与流体动力模型的计算之间的比较对系统的初始条件和运输特性施加了强大的限制。
Anisotropic flow coefficients, $v_n$, non-linear flow mode coefficients, $χ_{n,mk}$, and correlations among different symmetry planes, $ρ_{n,mk}$ are measured in Pb-Pb collisions at $\sqrt{s_\rm{NN}}=5.02$ TeV. Results obtained with multi-particle correlations are reported for the transverse momentum interval $0.2<p_\rm{T}<5.0$ GeV/$c$ within the pseudorapidity interval $0.4<|η|<0.8$ as a function of collision centrality. The $v_n$ coefficients and $χ_{n,mk}$ and $ρ_{n,mk}$ are presented up to the ninth and seventh harmonic order, respectively. Calculations suggest that the correlations measured in different symmetry planes and the non-linear flow mode coefficients are dependent on the shear and bulk viscosity to entropy ratios of the medium created in heavy-ion collisions. The comparison between these measurements and those at lower energies and calculations from hydrodynamic models places strong constraints on the initial conditions and transport properties of the system.
