标量暗物质的剧变衰变

Upsilon Decays into Scalar Dark Matter

Gagik K. Yeghiyan

摘要:

假设暗物质是由于重自由度的交换而产生的,我们研究了自旋为1的底鎓衰变为一对轻标量暗物质(DM)粒子。我们进行了独立于模型的分析,并推导出这些衰变的分支比的公式。我们将计算结果与实验数据进行了比较。我们表明,暗物质生产在Upperdum衰变可能会导致约束的参数模型包含一个轻自旋0 DM粒子。

英文摘要:

We examine decays of a spin-1 bottomonium into a pair of light scalar Dark Matter (DM) particles, assuming that Dark Matter is produced due to exchange of heavy degrees of freedom. We perform a model-independent analysis and derive formulae for the branching ratios of these decays. We confront our calculation results with the experimental data. We show that Dark Matter production in Upsilon decays may lead to constraints on parameters of the models containing a light spin-0 DM particle.
