复合希格斯粒子和暗物质的基本安全理论

Towards a fundamental safe theory of composite Higgs and Dark Matter

Giacomo Cacciapaglia, Teng Ma, Shahram Vatani, Yongcheng Wu

摘要:

我们提出了一种新的范式,允许定义一个复合理论在电弱尺度,定义良好的所有方式到任何能量的安全装置在紫外线。该理论从一个完整的UV固定点流到IR固定点的强动力学(这给出了所需的步行),然后在TeV尺度上产生质量间隙。我们讨论了两个模型,具有复合希格斯,暗物质和部分复合所有SM费米子。UV理论也可以嵌入到Pati-Salam部分统一中,从而消除了由$\mbox{U}(1)$运行产生的不稳定性。最后,我们发现一个暗物质候选者仍然允许在$260$ GeV,或$1.5 \sim 2$ TeV的质量,后者的质量范围将覆盖下一代直接检测实验。

英文摘要:

We present a novel paradigm that allows to define a composite theory at the electroweak scale that is well defined all the way up to any energy by means of safety in the UV. The theory flows from a complete UV fixed point to an IR fixed point for the strong dynamics (which gives the desired walking) before generating a mass gap at the TeV scale. We discuss two models featuring a composite Higgs, Dark Matter and partial compositeness for all SM fermions. The UV theories can also be embedded in a Pati-Salam partial unification, thus removing the instability generated by the $\mbox{U}(1)$ running. Finally, we find a Dark Matter candidate still allowed at masses of $260$ GeV, or $1.5 \sim 2$ TeV, where the latter mass range will be covered by next generation direct detection experiments.
