摘要

通过测量原子氙气中6a中子散射的角分布,得到了新的类重力短程相互作用的改进极限,其中散射势用yukawa型参数化模型来模拟。我们收集了大约$1.4 \ × 10^8$个小角度中子散射事件。这些数据被解释为没有新力的证据,并且在$0.3$ nm到$9$ nm的相互作用范围内,耦合强度的上限有所提高。这些改进的约束也被解释为一个模型的新极限,在这个模型中,新力的电荷被表示为重子数和轻子数的线性组合。

Experimental search for Non-Newtonian forces in the nanometer scale with slow neutrons
Improved limits for new gravity-like short-range interactions, in which a scattering potential is modeled by the Yukawa-type parametrization, have been obtained by measuring the angular distribution of 6 A neutrons scattering from atomic xenon gas. We have collected approximately $1.4 \times 10^8$ small-angle neutron scattering events. The data are interpreted as no evidence of new forces and show improved upper limits on the coupling strength in the interaction range of $0.3$ nm to $9$ nm. These improved constraints are also interpreted as new limits for a model, in which a charge of the new forces is expressed as a linear combination of the baryon number and the lepton number.
