论文摘要
最轻的超对称粒子（LSP）的高度Bino样暗物质（DM）可能是由DM直接检测率的严格上限动机的。当它的质量在100 GEV附近或低于100 GEV时，这种约束往往会变得最严重时，尤其如此。要求不那么大的higgsino质量参数，这会使场景合理地自然，这会促使这种类似Bino的状态相对轻。在最小的超级对称标准模型（MSSM）中，在没有相当轻的标量的情况下，如果必须是热液体，则这种激发将无法满足其丰度的严格实验上限，除非其自我净化会击中涉及$ Z $ -BOSON的渠道，否则涉及$ Z $ -Boson-Boson-boson-boson-boson-boson-boson-boson-boson-sm） - sm）-like-like-like-liks-liks boson。我们证明，在这种现实情况下，流行的$ z_3 $ - symmetric近代超对称标准模型（NMSSM）的高度Bino样DM在其质量的延长范围内是可行的，这是从我们对最大质量的最大群体的最大最大值，最高质量的最大值到大约30 GEV。这是通过具有相对轻的单线状态的存在来促进的，这些状态可以用作漏斗（标量）和/或凝集的状态（单利诺）状态，即使Bino-like LSP获得了最小的（但最佳的）调节，这是由适当轻的higgsino触发的，最初的降低范围很大，这是在其大规模上，这是在其大规模上的范围，这是从他们的大规模上散发出来的。存在较轻的单利诺式状态。 DM直接检测率是通过首次考虑Bino，Higgsinos和Singlino组成的增强系统来提出的一组盲点条件，该系统突出了NMSSMSM参数$λ$和$ \tanβ$在提供丰富的景观学方面发挥的重要作用。
A highly bino-like Dark Matter (DM), which is the Lightest Supersymmetric Particle (LSP), could be motivated by the stringent upper bounds on the DM direct detection rates. This is especially so when its mass is around or below 100 GeV for which such a bound tends to get most severe. Requiring not so large a higgsino mass parameter, that would render the scenario reasonably natural, prompts such a bino-like state to be relatively light. In the Minimal Supersymmetric Standard Model (MSSM), in the absence of comparably light scalars, such an excitation, if it has to be a thermal relic, is unable to meet the stringent experimental upper bound on its abundance unless its self-annihilation hits a funnel involving either the $Z$-boson or the Standard Model (SM)-like Higgs boson. We demonstrate that, in such a realistic situation, a highly bino-like DM of the popular $Z_3$-symmetric Next-to-Minimal Supersymmetric Standard Model (NMSSM) is viable over an extended range of its mass, from our targeted maximum in the vicinity of the mass of the top quark down to about 30 GeV. This is facilitated by the presence of comparably light singlet-like states that could serve as funnel (scalars) and/or coannihilating (singlino) states even as the bino-like LSP receives a minimal (but optimal) tempering triggered by suitably light higgsino states that, in the first place, evade stringent lower bounds on their masses that can be derived from the Large Hadron Collider (LHC) experiments only in the presence of a lighter singlino-like state. An involved set of blind spot conditions is derived for the DM direct detection rates by considering for the very first time the augmented system of neutralinos comprising of the bino, the higgsinos and the singlino which highlights the important roles played by the NMSSM parameters $λ$ and $\tanβ$ in delivering a richer phenomenology.
