论文摘要
我们从涉及超新星和中子星星合并中遇到的物质的反应中计算出轴突排放速率，确定独特的光谱特征，并探索它们对天体物理学和粒子物理学的影响。我们发现，它比核子核子核子大约2-5倍，在过去的研究中，它被认为是主要过程。还发现轴心光谱要困难得多。一起，较大的速率和较高的轴轴能意味着在QCD轴的质量上有更强的结合，并且从附近的银河系超新星从大的地下中微子检测器中直接检测的前景更好。
We calculate the axion emission rate from reactions involving thermal pions in matter encountered in supernovae and neutron star mergers, identify unique spectral features, and explore their implications for astrophysics and particle physics. We find that it is about 2-5 times larger than nucleon-nucleon bremsstrahlung, which in past studies was considered to be the dominant process. The axion spectrum is also found be much harder. Together, the larger rates and higher axion energies imply a stronger bound on the mass of the QCD axion, and better prospects for direct detection in a large underground neutrino detector from a nearby galactic supernova.
