摘要:

通过测量球和板的正弦波纹表面之间的法向和侧向Casimir力,我们得到了类轴子与核子的耦合常数的更强的实验室约束.为此,计算了在实验组态中由于质子和中子之间的两个轴子交换而产生的法向和侧向附加力。我们的约束以下的正常和横向卡西米尔力的测量是强于实验室的限制,迄今为止报道的质量大于11 eV和8 eV的类轴子粒子,分别。在类轴子质量从10^{-10}eV到20 eV的宽范围内,对由磁强计测量、Eotvos和Cavendish型实验以及Casimir效应得到的类轴子与核子的耦合常数的各种实验室约束条件进行了比较。

英文摘要:

We obtain stronger laboratory constraints on the coupling constants of axion-like particles to nucleons from measurements of the normal and lateral Casimir forces between sinusoidally corrugated surfaces of a sphere and a plate. For this purpose, the normal and lateral additional force arising in the experimental configurations due to two-axion exchange between protons and neutrons are calculated. Our constraints following from measurements of the normal and lateral Casimir forces are stronger than the laboratory constraints reported so far for masses of axion-like particles larger than 11eV and 8eV, respectively. A comparison between various laboratory constraints on the coupling constants of axion-like particles to nucleons obtained from the magnetometer measurements, Eotvos- and Cavendish-type experiments, and from the Casimir effect is performed over the wide range of masses of axion-like particles from 10^{-10}eV to 20eV.
