Abstract We present results from a search for solar axions with the COSINE-100 experiment. We find no evidence of solar axion events from a data-set of 6,303.9 kg · days exposure and set a 90% confidence level upper limit on the axion-electron coupling, gae, of 1.70 × 10 − 11 for an axion mass less than 1 keV/c2. This limit excludes QCD axions heavier than 0.59 eV/c2 in the DFSZ model and 168.1 eV/c2 in the KSVZ model.

用 COSINE-100 搜索太阳轴子诱导信号

摘要 我们展示了使用 COSINE-100 实验搜索太阳轴子的结果。我们从 6,303.9 kg · 天暴露的数据集中没有发现太阳轴子事件的证据,并为轴子质量小于 1 的轴子-电子耦合 gae 设置了 1.70 × 10 − 11 的 90% 置信水平上限keV/c2。此限制不包括 DFSZ 模型中重量超过 0.59 eV/c2 和 KSVZ 模型中 168.1 eV/c2 的 QCD 轴子。
