Flavenous Dark Sectors运行到低能量

Flavored Dark Sectors running to low energy

Martín Arteaga, Enrico Bertuzzo, Cristian Caniu Barros, Zahra Tabrizi

摘要:

我们考虑了由一个连接标准模型粒子到暗区的重介体产生的有效场论,明确考虑了算子的味结构。特别是,我们研究了模型独立运行和运营商之间的混合,以及他们在电弱尺度匹配。除了重整化群方程的显式表达式外,我们还给出了数值解以及一些有助于理解这些解的近似解析表达式。在低能量下,我们的结果在光暗扇区与b夸克通信的情况下特别重要,并且可以立即应用于调味暗物质。

英文摘要:

We consider the effective field theory generated by a heavy mediator that connects Standard Model particles to a Dark Sector, considering explicitly the flavor structure of the operators. In particular, we study the model independent running and mixing between operators, as well as their matching at the electroweak scale. In addition to the explicit expression of the Renormalization Group Equations, we show the numerical solutions as well as some approximate analytical expressions that help understanding these solutions. At low energy, our results are particularly important in the case of light dark sectors communicating to the b quark, and can be immediately applied to flavored Dark Matter.
