Yukawa效应对无阻力卫星上钟的影响

Yukawa effects on the clock onboard a drag-free satellite

Xue-Mei Deng, Yi Xie

摘要:

牛顿引力的汤川修正被认为是对引力平方反比定律的偏离的参数化,这种偏离可能是由粒子的标准模型和广义相对论之外的新物理学引起的。我们调查这些影响上的时钟板载无阻力卫星:动态的卫星和影响的时间传输链路。我们发现,在当前的时钟状态下,时间传递中的汤川信号比在轨道为$a=10^7$ 1,m和$e=0.01$的人造地球卫星上激光测距对动力学,特别是近星点长期变化的影响要难得多。

英文摘要:

The Yukawa correction to the Newtonian gravitational force is accepted as a parameterization of deviations from the inverse-square law of gravity which might be caused by new physics beyond the standard model of particles and the general theory of relativity. We investigate these effects on the clock onboard a drag-free satellite: dynamics of the satellite and influence on the time transfer link. We find the Yukawa signal in the time transfer is much harder to detect with current state of clocks than those effects on the dynamics, especially the secular change of periastron, by laser ranging in the case of an artificial Earth satellite carrying a frequency standard with an orbit of $a=10^7$\,m and $e=0.01$.
