MeV天文学与Herwig？
MeV astronomy with Herwig?
摘要：
GeV级的暗物质是一个越来越有吸引力的直接探测，间接探测和对撞机搜索的目标。特别是对于MeV到GeV范围内的质量，间接检测预计将成为主要的限制因素。在这个范围内，暗物质湮灭进入强子末态会产生一个充满挑战的轻强子共振动物园。更新Herwig 7，我们提供了一个模型，这些过程和研究的能量谱湮灭通过矢量介质。我们涵盖暗物质质量之间的250兆电子伏和5 GeV，包括误差估计。这为充分研究隐藏的暗物质部门的间接探测信号开辟了新的机会，矢量介质在亚GeV范围内。
英文摘要：
GeV-scale dark matter is an increasingly attractive target for direct detection, indirect detection, and collider searches. Especially for masses in the MeV to GeV range, indirect detection is expected to give a leading constraint. In that range, dark matter annihilations into hadronic final states produce a challenging zoo of light hadronic resonances. With an update of Herwig7, we provide a modeling of these processes and study energy spectra from annihilation through a vector mediator. We cover dark matter masses between 250 MeV and 5 GeV and include an error estimate. This opens up new opportunities for fully studying indirect detection signals for hidden dark matter sectors with vector mediators in the sub-GeV range.
