"SDn WIMP cross-section" of "A search for new physics in low-energy electron recoils from the first LZ exposure"

The observed 90% C.L. upper limit for the spin-dependent WIMP cross-section (cm^2) vs. WIMP mass (GeV/c^2) for coupling on neutrons. The result is obtained for WIMPs undergoing the Migdal effect from 0.5 to 9 GeV/c2. The data contains observed upper limit, median sensitivity and 1\sigma and 2\sigma sensitivity range as a function of WIMP Mass.

针对中子耦合的自旋依赖弱相互作用大质量粒子（Weakly Interacting Massive Particle，WIMP）截面（单位：cm²）的90%置信度（90% C.L.）上限随WIMP质量（单位：GeV/c²）的变化关系。该结果针对的是经历米格尔效应（Migdal effect）、质量范围为0.5至9 GeV/c²的WIMP。数据集包含随WIMP质量变化的观测上限、中位灵敏度以及1σ和2σ灵敏度范围。
