膜引力的经典检验

Classical tests in brane gravity

S. Jalalzadeh, M. Mehrnia, H. R. Sepangi

摘要:

膜引力中的真空解与4D中的真空解有许多附加项的不同,并且在小距离处简化为熟悉的史瓦西度规。我们研究了这些项在行星轨道岁差、光的弯曲、雷达延迟和试验天体平均运动异常中可能起的作用。利用太阳系实验的数据,我们确定了度规中与线性项相关的自由参数的范围。最好的结果来自行星平均运动的异常。这样的研究应该通过太阳系测试揭示暗能量的起源。

英文摘要:

The vacuum solutions in brane gravity differ from those in 4D by a number of additional terms and reduce to the familiar Schwarzschild metric at small distances. We study the possible roles that such terms may play in the precession of planetary orbits, bending of light, radar retardation and the anomaly in mean motion of test bodies. Using the available data from Solar System experiments, we determine the range of the free parameters associated with the linear term in the metric. The best results come from the anomalies in the mean motion of planets. Such studies should shed some light on the origin of dark energy via the solar system tests.
