标题： Generic multi-particle transverse momentum correlations as a new tool for studying nuclear structure at the energy frontier

摘要： 产生的粒子的平均横向动量 [pt] 及其逐事件涨落直接反映了超相对论重离子碰撞的初始条件，并有助于探测碰撞核的结构。 [pt] 的涨落可以通过多粒子 pt 相关性来研究；迄今为止，仅研究了最低的四个阶数。 高阶涨落可以对初始条件提供更强的约束，并提高对核详细结构的敏感性；然而，它们的直接实现可能具有挑战性，目前仍缺乏相关研究。 本文中，我们应用了一种通用的递归算法来研究真正的多粒子 pt 相关性，这使得首次能够准确地研究高阶 [pt] 涨落，而无需进行计算密集型处理。 通过这种方法，我们将通过不同核结构的 Monte Carlo 模型研究来检验多粒子 pt 相关性的能力。 我们将讨论其对核结构研究的影响，包括核变形和三轴结构。 这些结果将展示多粒子 pt 相关性在 RHIC 和 LHC 高能核碰撞中研究核结构的实用性，这可以作为现有低能核结构研究的补充。 显示英文摘要

摘要： The mean transverse momentum of produced particles, [pt], and its event-by-event fluctuations give direct access to the initial conditions of ultra-relativistic heavy-ion collisions and help probe the colliding nuclei's structure. The [pt] fluctuations can be studied via multi-particle pt correlations; so far, only the lowest four orders have been studied. Higher-order fluctuations can provide stronger constraints on the initial conditions and improved sensitivity to the detailed nuclear structure; however, their direct implementation can be challenging and is still lacking. In this paper, we apply a generic recursive algorithm for the genuine multi-particle pt correlations, which enables the accurate study of higher-order [pt] fluctuations without computationally heavy processing for the first time. With this algorithm, we will examine the power of multi-particle pt correlations through Monte Carlo model studies with different nuclear structures. The impact on the nuclear structure studies, including the nuclear deformation and triaxial structure, will be discussed. These results will demonstrate the usefulness of multi-particle pt correlations for studying nuclear structure in high-energy nuclei collisions at RHIC and the LHC, which could serve as complementary to existing low-energy nuclear structure studies.
