论文摘要
在超新星期间获得的高温和电子退化允许在所得的原始中子恒星的核心内形成大的雄性丰度。如果新的伪尺度自由度与穆恩具有很大的耦合，则可以通过这种哑光丰度产生它们，并有助于恒星的冷却。通过生成迄今为止使用MUON的最大的超新星模拟集合，我们表明，SN 1987a冷却速率的观察结果在类似轴突样粒子与Muons的耦合上构成了强大的限制，从而将耦合限制为$ G_ {Aμ} {Aμ} <10^10^{ - 7.5} { - 7.5}〜}〜\ fext text fext {
The high temperature and electron degeneracy attained during a supernova allow for the formation of a large muon abundance within the core of the resulting proto-neutron star. If new pseudoscalar degrees of freedom have large couplings to the muon, they can be produced by this muon abundance and contribute to the cooling of the star. By generating the largest collection of supernova simulations with muons to date, we show that observations of the cooling rate of SN 1987A place strong constraints on the coupling of axion-like particles to muons, limiting the coupling to $g_{aμ} < 10^{-7.5}~\text{GeV}^{-1}$.
