由双度规引力理论引起的大质量引力波的纵向分量
A longitudinal component in massive gravitational waves arising from a bimetric theory of gravity
摘要：
本文简要回顾了de Paula，Miranda和Marinho关于由双度规引力理论产生的大质量引力波的工作，指出质量的存在在波的特定偏振中产生一个纵向分量。这种极化对测试质量的影响是使用测地线偏差进行的。本文最后还讨论了这种特殊偏振的可探测性，表明如果现在或将来的探测器能达到很高的灵敏度，它的角度依赖性原则上可以把这种偏振与广义相对论的两种偏振区分开来。
英文摘要：
After a brief review of the work of de Paula, Miranda and Marinho on massive gravitational waves arising from a bimetric theory of gravity, in this paper it is shown that the presence of the mass generates a longi- tudinal component in a particular polarization of the wave. The effect of this polarization on test masses is performed using the geodesic deviation. A the end of this paper the detectability of this particular polarization is also discussed, showing that its angular dependence could, in princi- ple, discriminate such polarization with respect the two ones of general relativity, if present or future detectors will achieve a high sensitivity.
