标题： Effective Action for High-Energy Scattering in Gravity

摘要： 多Regge有效作用量直接从线性化引力作用量导出。 在排除了冗余的场分量后，我们将场分为动量模，并对既不对应于散射动力学也不对应于交换粒子动力学的模进行积分。 散射和粒子产生的有效顶点作为三重和四重相互作用项的贡献之和获得，有效作用量中的场是用度规涨落的两个物理分量定义的。 显示英文摘要

摘要： The multi-Regge effective action is derived directly from the linearized gravity action. After excluding the redundant field components we separate the fields into momentum modes and integrate over modes which correspond neither to the kinematics of scattering nor to the one of exchanged particles. The effective vertices of scattering and of particle production are obtained as sums of the contributions from the triple and quartic interaction terms and the fields in the effective action are defined in terms of the two physical components of the metric fluctuation.
