摘要提出了具有一般信使-物质相互作用的偏转异常调解场景下的自然SUSY辐射谱。由于新的相互作用的贡献，在任何一个偏转参数符号和很少的信使种的情况下，都可以自然地获得正的睡眠质量和大的|At|项（从而避免了可能的朗道极问题）。在这种情况下，与普通的（辐射）自然SUSY场景相比，暗物质（DM）的丰度不足，DM可以是混合的双higgsino，并且具有合适的遗迹密度。在我们的设想中，125 GeV的希格斯质量也很容易得到。XENON-1T直接探测实验可以覆盖大部分的低电子波微调点。
A bstractA 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 |At| 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.
