Abstract

We study dark matter scattering off \( ^4\)He and other light nuclei using chiral effective field theory. We consider scalar DM interactions and include both one- and two-nucleon scattering processes. The DM interactions and nuclear wave functions are obtained from chiral effective field theory and we work up to fourth order in the chiral expansion for the latter to investigate the chiral convergence. The results for the scattering rates can be used to determine the sensitivity of planned experiments to detect relatively light dark matter particles using \( ^4\)He. We find that next-to-leading-order scalar currents are smaller than expected from power counting for scattering off \( ^4\)He confirming earlier work. However, the results for two-nucleon corrections exhibit a linear regulator dependence indicating potential problems in the applied power counting. We observe a linear correlation between the, in principle not observable, D-wave probability of various light nuclei and the scalar two-nucleon matrix elements, again pointing towards potentially missing contributions.

手性有效场理论中暗物质对\( ^{4}\)He 的散射

我们利用手性有效场理论研究了暗物质对(^4\)He和其他轻核的散射。我们考虑了标量DM相互作用，包括单核和双核散射过程。DM相互作用和核波函数是从手性有效场理论中得到的，我们对后者进行了高达四阶的手性扩展，以研究手性收敛性。散射率的结果可以用来确定计划中使用 \( ^4\)He 探测相对较轻暗物质粒子的实验的灵敏度。我们发现，从 \( ^4\)He 散射的次导阶标量电流小于功率计数的预期，这证实了早期的工作。然而，双核修正的结果显示出线性调节器依赖性，这表明应用功率计数存在潜在问题。我们观察到原则上不可观测的各种轻核的 D 波概率与标量双核矩阵元素之间的线性相关，这再次表明可能存在缺失的贡献。
