论文摘要
我们研究了光标量暗物质的最小模型，需要一个光标量介质来解决Core-Cusp问题并与标准模型颗粒相互作用。我们通过重点关注BREIT-WIGNER共鸣，以实现暗物质歼灭和自散射通道来全面分析模型，考虑到包括早期动力学去耦效果的热式遗物丰度条件，以及对冲突，直接和间接暗物质检测的当前和未来限制。我们发现，质量为0.3-2 GEV的标量暗物质仍然未知，这将通过不久的将来的MEV伽马射线观测来有效地测试。
We study a minimal model for a light scalar dark matter, requiring a light scalar mediator to address the core-cusp problem and interact with the standard model particles. We analyze the model comprehensively by focusing on the Breit-Wigner resonance for dark matter annihilation and self-scattering channels, considering the thermal relic abundance condition that includes the early kinetic decoupling effect, as well as the present and future constraints from collider, direct, and indirect dark matter detections. We found that the scalar dark matter with the mass of 0.3-2 GeV remains uncharted, which will be efficiently tested by the near future MeV gamma-ray observations.
