论文摘要
我们引入了重粒子有效理论（HPET）的壳变量，其目的是将重型黑洞有效理论扩展到更高的自旋，并促进其在更高的胶后订单中的应用。这些变量继承了无旋转和自旋的含义效应与HPET场的分离，从而导致三分振幅的显式自旋 - 甲吡啶膨胀，以实现任何自旋的幅度。通过使用壳HPET变量表达的幅度与从一颗粒子有效动作中得出的幅度相匹配，我们发现，重型自旋粒子的自旋 - 摩尔型膨胀量完全对应于多极扩展（最多订购$ 2S $）的Kerr黑洞，而无需采取Infinite Spin Epinite spinitients spinitient。最后，我们表明，从重型旋转粒子发出的相同旋转玻色子的树级辐射过程表现出自旋 - 摩尔多杆的通用性。
We introduce on-shell variables for Heavy Particle Effective Theories (HPETs) with the goal of extending Heavy Black Hole Effective Theory to higher spins and of facilitating its application to higher post-Minkowskian orders. These variables inherit the separation of spinless and spin-inclusive effects from the HPET fields, resulting in an explicit spin-multipole expansion of the three-point amplitude for any spin. By matching amplitudes expressed using the on-shell HPET variables to those derived from the one-particle effective action, we find that the spin-multipole expansion of a heavy spin-$s$ particle corresponds exactly to the multipole expansion (up to order $2s$) of a Kerr black hole, that is, without needing to take the infinite spin limit. Finally, we show that tree-level radiative processes with same-helicity bosons emitted from a heavy spin-$s$ particle exhibit a spin-multipole universality.
