我们研究了最大程度隐形轴子的情况，即与物质相互作用仅源于解决强CP问题的与胶子的不可约耦合的QCD轴子。首先分析了这种轴子在核心坍缩超新星中的产生，推导了相应的SN 1987A冷却约束并计算了主要产生通道的发射光谱。然后研究了在切伦科夫探测器中探测最大程度隐形轴子的前景，以建立QCD轴子整体可探测性的稳健下限。
英文摘要
We investigate the scenario of maximally invisible axions, namely QCD axions whose interactions with matter arise exclusively from the irreducible coupling to gluons responsible for solving the strong-CP problem. We first analyze the production of such axions in core-collapse supernovae. In particular, we derive the corresponding SN 1987A cooling constraint and compute the emission spectra for the dominant production channels, namely nucleon-nucleon bremsstrahlung and pion conversion. We then investigate the prospects for detecting maximally invisible axions in Cherenkov detectors, with the goal of establishing a robust lower bound on the overall detectability of QCD axions.
