本文在自由场理论的水平上考虑了双场论的不变大质量形变.我们研究了上的Kaluza-Klein约化,并导出了每种螺旋度模的对角化二级作用量.在不存在鬼子和快子的条件下,我们得到了一类相容性条件,其中包括双场论中著名的弱约束作为特例。因此,我们找到了不变的Fierz-Pauli质量引力理论的双参数集。
We consider aninvariant massive deformation of double field theory at the level of free theory. We study Kaluza-Klein reduction onand derive the diagonalized second order action for each helicity mode. Imposing the absence of ghosts and tachyons, we obtain a class of consistency conditions which include the well-known weak constraint in double field theory as a special case. Consequently, we find two-parameter sets ofinvariant Fierz-Pauli massive gravity theories.
