DarkCapPy: Dark matter capture and annihilation

DarkCapPy is a Python 3/Jupyter package for calculating rates associated with dark matter capture in the Earth, annihilation into light mediators, and the subsequent observable decay of the light mediators near the surface of the Earth. The package includes a calculation of the Sommerfeld enhancement at the center of the Earth and the timescale for capture–annihilation equilibrium. The code is open source and can be modified for other compact astronomical objects and mediator spins.

DarkCapPy是一款适配Python 3与Jupyter的软件包，可用于计算地球暗物质俘获、湮灭为轻媒介子，以及轻媒介子在地球表面附近发生的后续可观测衰变相关的速率。该软件包包含地球核心处的索末菲增强（Sommerfeld enhancement）计算，以及俘获-湮灭平衡的时间尺度计算。本代码为开源代码，可针对其他致密天体以及媒介子自旋进行适配修改。
