论文摘要
通过测量来自原子Xenon气体的6Å中子散射的角度分布，可以获得通过Yukawa型参数化建模的新型重力样短距离相互作用的提高散射电位。我们收集了大约$ 1.4 \ times 10^8 $小角度中子散射事件。数据被解释为没有新力量的证据，并显示出在$ 0.3 $ nm至$ 9 $ nm的相互作用范围内耦合强度的上限提高。这些改进的约束也被解释为模型的新限制，其中新力量的电荷表示为重子数和Lepton数字的线性组合。
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 Å 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.
