重力探测器B对Kaluza-Klein引力的约束

Constraints on Kaluza-Klein gravity from Gravity Probe B

J. M. Overduin, R. D. Everett, P. S. Wesson

摘要:

利用重力探测器B的大地岁差测量结果,在卡鲁扎-克莱因重力场中,对一个旋转的试验体进行了约束,使其偏离爱因斯坦的广义相对论的可能性增加了一个空间维度。我们认为两个已知的静态和球对称的解决方案的5D场方程(孤子和正则度量),并获得新的限制与每个自由参数。理论与观察一致,但在两种情况下都必须“接近4D”。

英文摘要:

Using measurements of geodetic precession from Gravity Probe B, we constrain possible departures from Einstein's General Relativity for a spinning test body in Kaluza-Klein gravity with one additional space dimension. We consider the two known static and spherically symmetric solutions of the 5D field equations (the soliton and canonical metrics) and obtain new limits on the free parameters associated with each. The theory is consistent with observation but must be "close to 4D" in both cases.
