论文摘要
半约束的NMSSM（SCNMSSM）或带有非普遍Higgs群众的NMSSM自然可以在当前的限制下预测轻质的暗物质，包括Higgs数据，Sparticle-Mass Bounds，Sperticle-Mass Bounds，Dark Matters Searches和Muon G-2等。 （$ 1 \！\厚\！62 $ gev）和隐形的希格斯腐烂。在这种情况下，我们发现：（i）对于LSP $ \ \tildeχ^0_1 $，可以有四个漏斗通知机制，这是$ h_2 $，$ z $，$ z $，$ h_1 $ and $ h_1 $和$ a_1 $漏斗。 （ii）对于$ h_1 $和$ a_1 $的漏斗，$ \tildeχ^0_1 $质量比12 GEV轻，而无形的希格斯衰减最多可以是$ 2 \％$。 （iii）对于$ H_2 $和$ Z $漏斗，具有正确的遗物密度，看不见的希格斯衰减最多可以分别分别为$ 0.4 \％\％\％\％\％\％$。 （iv）如果在HL-LHC上发现了无形的希格斯衰减，则可以将轻暗物质的四个漏斗通道机制被排除在外，$ \tildeχ^0_1 $是唯一的暗物质源。提出了四个基准点，一个用于每种机制，用于将来检查，并进行更新的实验结果。
The semi-constrained NMSSM (scNMSSM), or NMSSM with non-universal Higgs masses, can naturally predict a light dark matter under current constraints including Higgs data, sparticle-mass bounds, dark matter searches, and muon g-2, etc. In this work, we take this scenario of scNMSSM as an example to study the funnel-annihilation mechanisms of light dark matter ($1\!\thicksim\!62$ GeV) and the invisible Higgs decay. In this scenario we found that: (i) There can be four funnel-annihilation mechanisms for the LSP $\tildeχ^0_1$, which are the $h_2$, $Z$, $h_1$ and $a_1$ funnel. (ii) For the $h_1$ and $a_1$ funnel with right relic density, the $\tildeχ^0_1$ mass is lighter than 12 GeV, and the invisible Higgs decay can be $2\%$ at most. (iii) For the $h_2$ and $Z$ funnel with right relic density, the invisible Higgs decay can be about $0.4\%$ and $1\%$ respectively at most. (iv) If the invisible Higgs decay was discovered at the HL-LHC, the four funnel-annihilation mechanisms of light dark matter may be all excluded with $\tildeχ^0_1$ as the only dark matter source. Four benchmark points, one for each mechanism, are proposed for future checking with updated experimental results.
