摘要

与核子耦合的类轴子粒子(ALPs)可能从超新星(SN)核心大量发射。我们将既有的自由流ALPs限制扩展到这些ALPs与核物质强相互作用而被囚禁于SN核心的情形。对于强相互作用ALPs,我们还扩展了基于SN 1987A时刻Kamiokande-II中微子探测器中无ALP诱导信号的约束。我们发现综合不同论证,SNe排除了ALP—核子耦合gaN109g_{aN}\gtrsim10^{-9}(对应ALP质量ma1MeVm_a\lesssim 1\,\mathrm{MeV})的取值。值得注意的是,对于标准QCD轴子模型,SN约束排除了所有ma102eVm_a \gtrsim 10^{-2}\,\mathrm{eV}的取值。该结果排除了当前与未来宇宙学巡天探测由热暗物质QCD轴子质量所致任何信号的可能性。

备注

15 pages, 7 figures. Matches the version published on PRD. Changes: we employed a different benchmark SN model with respect to the previous version, accounting for a 1D treatment of convection. We added a new section to discuss the uncertainties on the SN bounds. We added an additional section to analyze SN bounds on canonical QCD axion models
