论文摘要
最近的理论进步使QCD轴成为更强的候选暗物质，尤其是在$μ\ text {ev} $范围内。尽管腔卤代在排除$ 1-100 \μ\ text {ev} $区域中排除QCD轴的取得了重大进展，但$ 1 \ text {pev} -1 \μ\ text {ev} $ region仍然无法探索。 DMRADIO程序由一系列旨在探测低质量轴的实验组成。 DMradio-50L使用1吨平均场环形磁体和高Q LC振荡器，对$ G_ {Aγγ} <5 \ Times10^{ - 15} \ text {gev}^{ - 1}^{ - 1} $ 5 kHz和5 mHz之间具有目标敏感性。 DMRADIO-M $^3 $由4 T峰场电磁磁铁中的较高频率LC振荡器组成，对QCD轴的DFSZ模型的敏感性在30 MHz和200 MHz之间。在这项工作中，我们介绍了DMRADIO-50L和DMRADIO-M $^3 $的状态。
Recent theoretical advancements have made the QCD axion a stronger dark matter candidate, especially in the sub-$μ\text{eV}$ range. While cavity haloscopes have made significant progress in excluding QCD axions in the $1 - 100\ μ\text{eV}$ region, the $1 \text{ peV} - 1\ μ\text{eV}$ region remains unexplored. The DMRadio program consists of a series of experiments designed to probe low mass axions. DMRadio-50L uses a 1 T average field toroidal magnet and a high-Q LC-oscillator with target sensitivity to axions of $g_{aγγ} <5\times10^{-15}\text{ GeV}^{-1}$ between 5 kHz and 5 MHz. DMRadio-m$^3$ consists of a higher frequency LC-oscillator in a 4 T peak field solenoidal magnet with sensitivity to the DFSZ model of QCD axions between 30 MHz and 200 MHz. In this work, we present the status of DMRadio-50L and DMRadio-m$^3$.
