The first searches for axions and axionlike particles with the Large Underground Xenon experiment are presented. Under the assumption of an axioelectric interaction in xenon, the coupling constant between axions and electrons g_{Ae} is tested using data collected in 2013 with an exposure totaling 95 live days ×118 kg. A double-sided, profile likelihood ratio statistic test excludes g_{Ae} larger than 3.5×10^{-12} (90% C.L.) for solar axions. Assuming the Dine-Fischler-Srednicki-Zhitnitsky theoretical description, the upper limit in coupling corresponds to an upper limit on axion mass of 0.12 eV/c^{2}, while for the Kim-Shifman-Vainshtein-Zhakharov description masses above 36.6 eV/c^{2} are excluded. For galactic axionlike particles, values of g_{Ae} larger than 4.2×10^{-13} are excluded for particle masses in the range 1-16 keV/c^{2}. These are the most stringent constraints to date for these interactions.
介绍了利用大型地下氙实验首次对轴子和类轴子粒子进行的搜索。在氙中存在轴电相互作用的假设下，利用2013年收集的数据对轴子与电子之间的耦合常数(g_{Ae})进行了测试，曝光总量为95个活日×118千克。对于太阳轴子，双侧轮廓似然比统计检验排除了(g_{Ae})大于(3.5×10^{-12})（90%置信水平）的情况。假设采用迪内 - 菲施勒 - 斯雷德尼茨基 - 日特尼茨基理论描述，耦合的上限对应于轴子质量的上限为(0.12)电子伏特/ (c^{2})，而对于金 - 希夫曼 - 瓦因施泰因 - 扎哈罗夫描述，排除了质量高于(36.6)电子伏特/ (c^{2})的情况。对于星系类轴子粒子，对于质量在1 - 16千电子伏特/ (c^{2})范围内的粒子，排除了(g_{Ae})大于(4.2×10^{-13})的值。这些是迄今为止对这些相互作用最严格的限制。
