强等效原理的引力波检验

Gravitational Wave Test of the Strong Equivalence Principle

C. S. Unnikrishnan, George T. Gillies

摘要:

强等效原理(SEP)是广义相对论作为非线性相对论引力理论的全部本质和意义。它断言万有引力与所有物质及其相互作用的普遍耦合,包括引力相互作用和引力自能。我们指出,确认引力耦合到引力子,从而引力波,是直接测试的SEP。我们表明,引力波和伽马射线的合并的双星中子星的近同时检测提供了一个独特的和最精确的测试的SEP,优于部分在$10^{9}$,这也是唯一的测试的SEP在辐射部门。

英文摘要:

The Strong Equivalence Principle (SEP) holds the full essence and meaning of the General Theory of Relativity as the nonlinear relativistic theory of gravitation. It asserts the universal coupling of gravity to all matter and its interactions including the gravitational interaction and the gravitational self energy. We point out that confirming the gravitational coupling to gravitons, and hence to the gravitational waves, is the direct test of the SEP. We show that the near simultaneous detection of gravitational waves and gamma rays from the merger of binary neutron stars provides a unique and the most precise test of the SEP, better than a part in $10^{9}$, which is also the only test of the SEP in the radiation sector.
