有挠的五维Kaluza—Klein理论和第五种力

FIVE-DIMENSIONAL KALUZA-KLEIN THEORY WITH TORSION AND THE FIFTH FORCE

以Riemann—Cartan时空为底流形,U(1)群为结构群的主纤维丛空间P作为有挠的五维Kaluza—Klein空间,构造引力、电磁规范场和第五种力的统一作用量,得到了相应的场方程。第五维的度规分量以及传播挠率解释为第五种力的时空效应。

Taking the principal fibre bundle P over Riemann - Cartan menifold with the group structure U(l)as Kaluza - Klein space,we construct an action for the unified system including gravitation,fifth force and gauge electromagnetic field,and derive the field equations using the action. The fifth dimensional component of the metric and the propagational torsion are considered as space-time effect of the fifth force.
