信使-物质相互作用下偏转AMSB情景的辐射自然SUSY谱
Radiative natural SUSY spectrum from deflected AMSB scenario with messenger-matter interactions
摘要:
在具有一般信使-物质相互作用的偏折异常调解方案中,提出了一个辐射自然超对称谱。由于新相互作用的贡献,正的slepton质量以及一个大的|A_t|项可以自然地获得与任何符号的偏转参数和很少的信使物种(从而避免可能的朗道极问题)。在这种情况下,相对于普通的(辐射)自然超对称性的暗物质(DM)的丰度不足的情况下,DM可以是混合bino-higgsino和有合适的遗迹密度。125 GeV的希格斯质量也可以很容易地在我们的场景中获得。氙-1T直接探测实验可以覆盖大多数低EW微调点。
英文摘要:
A radiative natural SUSY spectrum are proposed in the deflected anomaly mediation scenario with general messenger-matter interactions. Due to the contributions from the new interactions, positive slepton masses as well as a large |A_t| term can naturally be obtained with either sign of deflection parameter and few messenger species (thus avoid the possible Landau pole problem). In this scenario, in contrast to the ordinary (radiative) natural SUSY scenario with under-abundance of dark matter (DM), the DM can be the mixed bino-higgsino and have the right relic density. The 125 GeV Higgs mass can also be easily obtained in our scenario. The majority of low EW fine tuning points can be covered by the XENON-1T direct detection experiments.
