摘要:

证明了新的大质量引力--由Bergshoeff,Hohm和Townsend(BHT)提出的大质量三维引力模型--是唯一可以通过曲率平方项扩充平面引力而构造的树级么正系统。BHT模型的两个有趣的引力性质,即时间膨胀和时间延迟,这是没有对应的,在通常的爱因斯坦三维引力,以及进行了分析。

英文摘要:

A proof that new massive gravity - the massive 3D gravity model proposed by Bergshoeff, Hohm and Townsend (BHT) - is the only unitary system at the tree level that can be constructed by augmenting planar gravity through the curvature-squared terms, is presented. Two interesting gravitational properties of the BHT model, namely, time dilation and time delay, which have no counterpart in the usual Einstein 3D gravity, are analyzed as well.
