论文摘要
使用有效的现场理论框架的最新工作表明，核子之间可能的耦合数量和深色抗性弱相互作用的巨大颗粒（WIMP）比以前想象的要大。受到计算目标响应的现有Mathematica脚本的启发，我们开发了一种快速，现代的FORTRAN代码，包括可选的OpenMP并行化以及用户友好的Python包装器，以迅速有效地探索许多方案，并与当前暗物质搜索的实践保持一致。包括大多数重要目标核素的库；用户还可以以减少的一体密度矩阵的形式导入自己的核结构数据。主要输出是差分事件速率是对后坐力能量的函数，这是对检测器响应率进行建模所需的，但是可以轻松访问诸如核形态之类的中间结果。
Recent work, using an effective field theory framework, has shown the number of possible couplings between nucleons and the dark-matter-candidate Weakly Interacting Massive Particles (WIMPs) is larger than previously thought. Inspired by an existing Mathematica script that computes the target response, we have developed a fast, modern Fortran code, including optional OpenMP parallelization, along with a user-friendly Python wrapper, to swiftly and efficiently explore many scenarios, with output aligned with practices of current dark matter searches. A library of most of the important target nuclides is included; users may also import their own nuclear structure data, in the form of reduced one-body density matrices. The main output is the differential event rate as a function of recoil energy, needed for modeling detector response rates, but intermediate results such as nuclear form factors can be readily accessed.
