论文摘要
我们考虑使用最小的palatini作用的Riemann-Cartan重力，这在经典上等同于爱因斯坦的重力。遵循L.lipatov \ cite {lipgrav}的思想，我们提出了该理论的有效作用，旨在描述多种运动学中引力颗粒的高能量散射。为此，我们添加到Palatini行动中，负责重力量子与某些集体激发的相互作用的新术语，这些激发替代了多种重力激发。我们基于与QCD的雷格恩领域理论的类比，提出对其特定形式的启发式解释。我们认为，Regge运动学假设出现了一个有效的两个维度模型，该模型描述了与QCD相似的高能量散射。这样的模型可以以一种导致我们最终有效理论的方式提出，该理论包含了自旋连接的普通量子与Vielbein之间的相互作用与他们假装重力重物的作用的有效对应物之间的相互作用。
We consider Riemann-Cartan gravity with minimal Palatini action, which is classically equivalent to Einstein gravity. Following the ideas of L.Lipatov \cite{LipGrav} we propose the effective action for this theory aimed at the description of the high-energy scattering of gravitating particles in the multi - Regge kinematics. For that purpose we add to the Palatini action the new terms responsible for the interaction of gravitational quanta with certain collective excitations that replace exchange by multiple gravitational excitations. We propose the heuristic explanation of its particular form based on an analogy to the reggeon field theory of QCD. We argue that Regge kinematics assumes the appearance of an effective two - dimensional model describing the high - energy scattering similar to that of QCD. Such a model may be formulated in a way leading to our final effective theory, which contains interaction between the ordinary quanta of spin connection and vielbein with their effective counterparts that pretend to the role of the gravitational reggeons.
