论文摘要
这封信报告了台湾轴心搜索实验的第一个结果，该实验是haloscope的，这是在4.70750和4.79815 GHz之间使用微波腔的轴搜索。除非非轴心信号外，没有发现显着性超过3.355的候选人。该实验排除了具有轴轴轴耦合$ \ weft | g_ {aγγ} \右| \ gtrsim 8.2 \ times 10^{ - 14} $ gev $^{ - 1} $的模型，比在基准ksvz模型上的一个范围更好的范围7，该范围的范围更好。 $ m_a $ <19.8436 $μ$ ev。这也是第一次在该质量区域将haloscope-type实验对$ g_ {aγγ} $放置。
This Letter reports on the first results from the Taiwan Axion Search Experiment with Haloscope, a search for axions using a microwave cavity at frequencies between 4.70750 and 4.79815 GHz. Apart from the non-axion signals, no candidates with a significance more than 3.355 were found. The experiment excludes models with the axion-two-photon coupling $\left|g_{aγγ}\right|\gtrsim 8.2\times 10^{-14}$ GeV$^{-1}$, a factor of eleven above the benchmark KSVZ model, reaching a sensitivity three orders of magnitude better than any existing limits in the mass range 19.4687 < $m_a$ < 19.8436 $μ$eV. It is also the first time that a haloscope-type experiment places constraints on $g_{aγγ}$ in this mass region.
