论文摘要
我们考虑将大型电动sudakov对数重新召集,以用$ \ Mathcal {O} $(TEV)质量歼灭Neutmalino DM,以最小的超对称标准模型中的高能量光子,从而扩展了先前在最小Wino和Higgsino型号上的工作。我们发现,NLL重新召集的光子的产量降低了Higgsino主导的DM的$ 20 \%$,大众在1点tev左右,最高$ 45 \%$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $,在3岁tev附近的Heaver块中具有较大Wino混合物的较大Wino混合物。当将观测值或排除限制转换为MSSM参数空间约束时,这种相当大的效果是相关的。
We consider the resummation of large electroweak Sudakov logarithms for the annihilation of neutralino DM with $\mathcal{O}$(TeV) mass to high-energy photons in the minimal supersymmetric standard model, extending previous work on the minimal wino and Higgsino models. We find that NLL resummation reduces the yield of photons by about $20\%$ for Higgsino-dominated DM at masses around 1~TeV, and up to $45\%$ for neutralinos with larger wino admixture at heavier masses near 3~TeV. This sizable effect is relevant when observations or exclusion limits are translated into MSSM parameter-space constraints.
