摘要:

本文讨论了用球-板组态间接测量平行板间Casimir压力所得到的Yukawa相互作用参数的约束条件。最近有文献指出,用邻近力近似(PFA)计算球板位形中的Yukawa相互作用时,所得的约束条件会产生100%量级的误差。在这里,我们重新计算的约束,无论是准确的,并使用PFA,并得出相同的结果。我们阐明了得出错误结论的原因,表明PFA不适用于计算汤川力。

英文摘要:

We discuss the constraints on the parameters of a Yukawa interaction obtained from the indirect measurements of the Casimir pressure between parallel plates using the sphere-plate configuration. Recently, it was claimed in the literature that the application of the proximity force approximation (PFA) to the calculation of a Yukawa interaction in the sphere-plate configuration could lead to a large error of order 100\% in the constraints obtained. Here we re-calculate the constraints both exactly and using the PFA, and arrive at identical results. We elucidate the reasons why an incorrect conclusion was obtained suggesting that the PFA is inapplicable to calculate the Yukawa force.
