论文摘要
一些有效的田间理论表现出动态共鸣，如果正确地包括，则可以在高能量下减轻其不良行为。部分波幅度的单位化是公布此类共振的首选方法。我们以有效的拉格朗日的精神来解释爱因斯坦 - 希尔伯特的理论，我们实施了反向振幅方法，并将纯净性重力的一环级别graviton-graviton graviton散射。由于存在红外差异，该分析需要对红外区域进行仔细处理，并引入红外调节剂，并精心选择以实现扰动单位性。与最近的一项研究相矛盾，没有发现任何质博式的证据。
Some effective field theories exhibit dynamical resonances that, when properly included, mitigate their bad behaviour at high energies. Unitarization of the partial wave amplitudes is the preferred method to unveil such resonances. Interpreting the Einstein-Hilbert theory in the spirit of effective Lagrangians, we implement the Inverse Amplitude Method and unitarize the one-loop level graviton-graviton scattering in pure gravity. Due to the presence of infrared divergences, the analysis requires a careful treatment of the infrared region and the introduction of infrared regulators, carefully selected in order to fulfil perturbative unitarity. No evidence of any graviball is found, in contradiction with a recent study.
