论文摘要
我们探索了太阳轴的一种新颖的检测可能性，该检测可能仅依赖于它们与核子的耦合，这是通过轴突诱导的Deuteron的解离到其组成中子和质子中的。此过程的一个适当目标是现已结合的萨德伯里中微子天文台（SNO）实验，该实验依靠大量的重水来解决太阳中微子问题。从完整的SNO数据集中，我们以独立于模型的时尚等级轴轴 - 核素耦合$ | g^3_ {an} | \ equiv \ equAc {1} {2} {2} | g_ {an} -g_ {an} -g_g_ {ap {ap {ap {ap> 2 \ 5}^{ - 5} $ g { - g_ g_ {2} $ g { - 对于子-MEV轴支质量，涵盖了轴突参数空间的先前未开发的区域。在$ g_ {an} $和$ g_ {ap} $之间没有精确取消的情况下，此结果也超过了其他实验室实验的可比约束，并且不包括SN1987A和Neuton Star从SN1987A和Neutmon Star冷却的参数空间的区域，这是由于轴心不适用的。
We explore a novel detection possibility for solar axions, which relies only on their couplings to nucleons, via the axion-induced dissociation of deuterons into their constituent neutrons and protons. An opportune target for this process is the now-concluded Sudbury Neutrino Observatory (SNO) experiment, which relied upon large quantities of heavy water to resolve the solar neutrino problem. From the full SNO dataset we exclude in a model-independent fashion isovector axion-nucleon couplings $|g^3_{aN}|\equiv\frac{1}{2}|g_{an}-g_{ap}|>2\times10^{-5}$GeV${}^{-1}$ at 95 % C.L. for sub-MeV axion masses, covering previously unexplored regions of the axion parameter space. In the absence of a precise cancellation between $g_{an}$ and $g_{ap}$ this result also exceeds comparable constraints from other laboratory experiments, and excludes regions of the parameter space for which astrophysical constraints from SN1987A and neutron star cooling are inapplicable due to axion trapping.
