论文摘要
如果暗物质（DM）的歼灭产物是非权利主义的，并且直接与光力介体直接伴侣，则必须考虑使用非扰动效应，例如最终状态结合状态（FBS）形成和最终状态Sommerfeld（FSS）效应。当DM和产品之间存在少量质量时，将出现最终颗粒的非相关区域，因此我们使用两个特定模型研究了质量质量区域（包括运动学案例）中的这些影响。我们证明，与某些质量分裂区域的标准扰动计算相比，FBS效应将显着改变DM遗物丰度。我们强调，在那些质量分裂中，FBS效应与FSS效应相当。考虑到FBS的形成，保护角动量是微妙的，在某些情况下可能没有$ S $ - 波浪，因此我们使用两种模型表现出不同的部分波FBS效应贡献。我们还表明，具有向量玻色子排放过程的FBS组也有助于DM遗物丰度，并首先计算特定模型中的$ p $ -Wave FSS效应。
If the annihilation products of dark matter (DM) are non-relativistic and couples directly to a light force mediator, the non-perturbation effect like final state bound state (FBS) formation and final state Sommerfeld (FSS) effect must be considered. Non-relativistic region of final particles will appear when there is small mass split between DM and products, so we study those effects in the degenerate region of mass (including kinematics forbidden case) using two specific models. We demonstrate that FBS effect will significantly modify the DM relic abundance comparing to the standard perturbation calculation in some mass split region. We emphasize that FBS effect is comparable to the FSS effect in those mass split. The conservation angular momentum are subtle considering FBS formation, in some cases there may be not $s$-wave, so we use two models exhibit the different partial wave FBS effect contribution. We also show that the FBS formation with vector boson emission process also contributes in DM relic abundance, and first calculate the $p$-wave FSS effect in the specific model.
