论文摘要

对于最小的Wino和Higgsino基准模型,我们通过合并Electroweak Sudakov在最大能量的electroweak Sudakov与Electroweak Parton-Share Parton-shower PPPC4DM和sommerfeld效应效应的Electroweak sudakov重新启动,从TEV量表深色succe $χ\χ\到γ+x $的高能量光谱。 electroweak重新召集显着改变了宽范围内光子 - 能谱的形状,$e_γ\ sim(0.6 \ ldots 1)\,m_χ$,因此是所谓的“线信号”的形式。

For the minimal wino and Higgsino benchmark models we provide accurate energy spectra of high-energy photons from TeV scale dark-matter annihilation $χχ\to γ+X$ by merging electroweak Sudakov resummation near maximal energy with the electroweak parton-shower PPPC4DM, and accounting for the Sommerfeld effect. Electroweak resummation significantly changes the shape of the photon-energy spectrum in the wide range $E_γ\sim (0.6\ldots 1)\, m_χ$ and hence the form of the so-called "line-signal".
