希格斯门到脉冲星坍缩
Higgs portals to pulsar collapse
摘要：
从银河系中心明显消失的脉冲星可能已经被非对称费米子暗物质（$m_X = 1-100$ GeV）与光标量（$m_ϕ= 5-20$ MeV）耦合破坏，光标量与希格斯玻色子混合。我们指出，这个脉冲星坍缩暗扇区可以解决核心尖点问题，并将被排除或发现即将进行的直接检测实验。另一个含义是脉冲星的最大年龄曲线随着距离银河系中心的距离而增加，其标准化取决于暗区粒子的耦合和质量。此外，我们使用旧的银河系中心以外的希格斯门模型的界限。
英文摘要：
Pulsars apparently missing from the galactic center could have been destroyed by asymmetric fermionic dark matter ($m_X = 1-100$ GeV) coupled to a light scalar ($m_ϕ= 5-20$ MeV), which mixes with the Higgs boson. We point out that this pulsar-collapsing dark sector can resolve the core-cusp problem and will either be excluded or discovered by upcoming direct detection experiments. Another implication is a maximum pulsar age curve that increases with distance from the galactic center, with a normalization that depends on the couplings and masses of dark sector particles. In addition, we use old pulsars outside the galactic center to place bounds on asymmetric Higgs portal models.
