论文摘要
高阶谐波流量可观察$ v_n $($ n> 3 $)及其对初始状态各向异性的非线性响应具有限制剪切粘度和散装粘度与熵比的强大潜力,因为对重型离子碰撞的各个阶段的敏感性不同。流量系数和非线性系数的测量值分别为第九和第五谐波,在$ \ sqrt {s_ \ mathrm {nn}} = 5.02 \,\ sqrt {s_ \ mathrm {nn}} = 5.02 \,\ sqrt {s_ \ mathrm {nn}}中呈现。此外,$ p_ \ mathrm {t} $的结果 - $π^\ pm $,$ \ mathrm {k}^\ pm $,$ \ mathrm {p}+\ mathrm { $λ+\barλ_s^0 $和$ ϕ $。将结果与2.76 TEV的相同测量结果进行了比较,并从最先进的流体动力学模型中进行了计算。
The higher order harmonic flow observables $v_n$ ($n > 3$) and their non-linear responses to the initial state anisotropy have the strong potential to constrain shear and bulk viscosity to entropy ratios because of different sensitivities for various stages of heavy-ion collisions. The measurements of the flow coefficients and the non-linear coefficients up to the ninth and fifth harmonic, respectively, are presented in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02\,\mathrm{TeV}$ for charged hadrons. In addition, the results of $p_\mathrm{T}$-differential non-linear flow modes for $π^\pm$, $\mathrm{K}^\pm$, $\mathrm{p}+\mathrm{\bar{p}}$, $\mathrm{K}_s^0$, $Λ+\barΛ_s^0$ and $ϕ$ are presented. The results are compared to the same measurements at 2.76 TeV and calculations from state of the art hydrodynamic models.
