引力的Clifford代数规范不变拉格朗日量。第2部分:与广义相对论测试的兼容性

A Clifford algebra gauge invariant Lagrangian for gravity. Part 2 : compatibility with General Relativity tests

Jean Pierre Pansart

摘要:

与标准二次规范场拉格朗日量一起使用的狄拉克矩阵代数相关的规范场导致了一个扩展的引力拉格朗日量,其中包括爱因斯坦-希尔伯特量,加上二次项,宇宙学常数和扭转项。本文考察了三种情况:静态中心对称场、各向同性膨胀宇宙和旋转体的渐近场,并表明,在弱引力场,这与广义相对论的结果并不矛盾。

英文摘要:

Gauge fields associated to the Dirac matrix algebra used with the standard quadratic gauge field Lagrangian lead to an extended gravitational Lagrangian which includes the Einstein-Hilbert one, plus quadratic, cosmological constant and torsion terms. This note looks at three cases : the static central symmetric field, the isotropic expanding universe, and the asymptotic field of a rotating body, and show that, in weak gravitational fields, there is no contradiction with General Relativity results.
