论文摘要
我们考虑了一个模型，该模型在基本表示中具有SP Dark Gauge组和一个标量字段，该模型得益于全球U（1）意外对称性，从而导致两个在扰动级别的共同稳定DM候选者。在低能量尺度的量规限制之后，两个候选者中只有一个仍然稳定。我们通过数值求解玻尔兹曼方程来计算DM遗物丰度。浅深胶球的存在会产生额外的宇宙学效果，并可能影响希格斯物理学。我们研究了DM现象学，为直接检测和间接检测提供了预测（包括Sommerfeld增强）。我们表明，该模型可以预测与通常的WIMPS范式相比，间接检测横截面略有抑制。
We consider a model with Sp dark gauge group and a scalar field in the fundamental representation, which leads to two co-stable DM candidates at the perturbative level thanks to a global U(1) accidental symmetry. After gauge confinement at low energy scale, only one of the two candidates is still stable. We compute the DM relic abundance by solving the Boltzmann equations numerically. The presence of light dark glueballs gives extra cosmological effects and can affect Higgs physics. We study the DM phenomenology, providing the predictions for direct and indirect detection (including the Sommerfeld enhancement). We show that the model predicts a slightly suppressed indirect detection cross section in comparison to the usual WIMPs paradigm.
