经典物体运动在平坦时空和有效弯曲时空中的量子Yang-Mills引力

Quantum Yang-Mills gravity in flat space-time and effective curved space-time for motions of classical objects

Jong-Ping Hsu

摘要:

平直时空中平移规范群T(4)的杨-米尔斯引力意味着引力子的简单自耦合和真正守恒的能量-动量张量。它与实验的一致性关键取决于一个有趣的性质,即“有效黎曼度量张量”出现在且仅出现在光子和粒子波方程的几何光学极限中。我们得到了引力子-费米子耦合系统的费曼定则,其中包括具有两个规范参数的一般引力子传播子和鬼粒子的相互作用。作为N体系统的宏观物体的运动方程被证明是费米子波动方程的几何光学极限。本文讨论了经典粒子的具有有效黎曼度规张量的相对论性Hamilton-Jacobi方程。

英文摘要:

Yang-Mills gravity with translational gauge group T(4) in flat space-time implies a simple self-coupling of gravitons and a truly conserved energy-momentum tensor. Its consistency with experiments crucially depends on an interesting property that an `effective Riemannian metric tensor' emerges in and only in the geometric-optics limit of the photon and particle wave equations. We obtain Feynman rules for a coupled graviton-fermion system, including a general graviton propagator with two gauge parameters and the interaction of ghost particles. The equation of motion of macroscopic objects, as an N-body system, is demonstrated as the geometric-optics limit of the fermion wave equation. We discuss a relativistic Hamilton-Jacobi equation with an `effective Riemann metric tensor' for the classical particles.
