论文摘要
$^{96} _ {44} $ ru+$^{96} _ {44} $ ru和$^{96} _ {40} $ zr+$^{96} _ {40} $ zr collisions at $ \ sqrt {从碰撞核的变形中引起的几何形状和波动。 Using iEBE-VISHNU hybrid model, we predict ${\rm ac}_{2}\{3\}$ ratios between these two collision systems and demonstrate that the ratios of ${\rm ac}_{2}\{3\}$, as well as the ratios of the involving flow harmonics and event-plane correlations, are sensitive to quadrupole和Octupole变形，可以对$^{96} $ ru和$^{96} $ zr之间的形状差异提供强大的约束。我们还研究了非线性响应系数$χ_{4,22} $，这对变形效应表示不敏感。
$^{96}_{44}$Ru+$^{96}_{44}$Ru and $^{96}_{40}$Zr+$^{96}_{40}$Zr collisions at $\sqrt{s_{_{\rm NN}}}=200$ GeV provide unique opportunities to study the geometry and fluctuations raised from the deformation of the colliding nuclei. Using iEBE-VISHNU hybrid model, we predict ${\rm ac}_{2}\{3\}$ ratios between these two collision systems and demonstrate that the ratios of ${\rm ac}_{2}\{3\}$, as well as the ratios of the involving flow harmonics and event-plane correlations, are sensitive to quadrupole and octupole deformations, which could provide strong constrains on the shape differences between $^{96}$Ru and $^{96}$Zr. We also study the nonlinear response coefficients $χ_{4,22}$, which show insensitivity to the deformation effect.
