Axion Hunters的恒星食谱
Stellar Recipes for Axion Hunters
摘要：
天体物理学的许多观测线索表明，除了中微子发射之外，恒星还存在能量损失。这些过多的能量损失可以解释为存在一个新的亚千电子伏质量的赝标量Nambu-Goldstone玻色子与光子，电子和核子的微小耦合。一个有吸引力的可能性是确定这个粒子与轴子-假设的伪Nambu-Goldstone玻色子预测的Peccei-Quinn解决方案的强CP问题。我们探讨这种可能性的DFSZ型轴子和KSVZ型轴子/majoron，分别。这两种模型都允许一个很好的全球拟合的数据，更喜欢一个轴子质量约10兆电子伏。我们表明，未来的轴子实验-第五力实验ARIADNE和日光镜IAXO -可以攻击的首选质量范围从低端和高端，分别。在这个质量范围内的轴子也可以是暗物质的主要成分。
英文摘要：
There are a number of observational hints from astrophysics which point to the existence of stellar energy losses beyond the ones accounted for by neutrino emission. These excessive energy losses may be explained by the existence of a new sub-keV mass pseudoscalar Nambu--Goldstone boson with tiny couplings to photons, electrons, and nucleons. An attractive possibility is to identify this particle with the axion -- the hypothetical pseudo Nambu--Goldstone boson predicted by the Peccei--Quinn solution to the strong CP problem. We explore this possibility in terms of a DFSZ-type axion and of a KSVZ-type axion/majoron, respectively. Both models allow a good global fit to the data, prefering an axion mass around 10 meV. We show that future axion experiments -- the fifth force experiment ARIADNE and the helioscope IAXO -- can attack the preferred mass range from the lower and higher end, respectively. An axion in this mass range can also be the main constituent of dark matter.
