标题： Wee partons in QCD and gravity: double copy and universality

摘要： 我们讨论了爱因斯坦引力和量子色动力学（QCD）中冲击波碰撞辐射之间的定量“双拷贝”关系。 该对应关系扩展到了Regge渐近线中的$2\rightarrow N$幅度。 这些幅度在最大占据数的经典化和单位化，分别对应于黑洞和Color Glass Condensate（CGC）态，由wee部分子的涌现Goldstone动力学描述。 我们概述了这种对应关系两边的普遍动力学的一些后果。 显示英文摘要

摘要： We discuss a quantitative "double copy" between radiation from shockwave collisions in Einstein gravity and in QCD. The correspondence extends to $2\rightarrow N$ amplitudes in Regge asymptotics. The classicalization and unitarization of these amplitudes at maximal occupancy, corresponding to black hole and Color Glass Condensate (CGC) states respectively, are described by the emergent Goldstone dynamics of wee partons. We outline some consequences of the universal dynamics on both sides of the correspondence.
