论文摘要
我们首次研究了核波功能中集体量子效应对方位各向异性系数$ε_{2,3} $在LHC Energies中中央PB+PB碰撞中的影响。在能量加权和规则的帮助下，我们证明了木材撒克逊核密度的经典处理高估了$^{208} $ Pb核的均方四极矩矩均为$ \ sim 2.2 $。中央PB+PB碰撞的蒙特卡洛·格劳伯（Monte-Carlo Glauber）模拟了四极力矩的限制，导致$ε_2/ε_3\约0.8 $，这允许解决$ v_2 $ -v_2 $ -to-to- $ v_3 $拼图。
We have studied, for the first time, the influence of the collective quantum effects in the nuclear wave functions on the azimuthal anisotropy coefficients $ε_{2,3}$ in the central Pb+Pb collisions at the LHC energies. With the help of the energy weighted sum rule we demonstrate that the classical treatment with the Woods-Saxon nuclear density overestimates the mean square quadrupole moment of the $^{208}$Pb nucleus by a factor of $\sim 2.2$. The Monte-Carlo Glauber simulation of the central Pb+Pb collisions accounting for the restriction on the quadrupole moment leads to $ε_2/ε_3\approx 0.8$ which allows to resolve the $v_2$-to-$v_3$ puzzle.
