论文摘要
我们研究了在近右手中微子（NMSSMR）的近乎微调超对称标准模型中测量中微子Yukawa耦合的可能性，而最轻的超对称伙伴（右手sneutrino）是通过利用dijet + dijet + dillepton + transervers的候选者（右手的sneutrino）是暗物质（DM）候选人（DM）候选人（MIS）。我们表明，与超对称性（SUSY）（即MSSM）不同，DM候选人是一个更重的（费尔米金）状态（中inorino）的MSSM，这种非最低点的Susy模型可以提供更轻（Bosonic）州（Bosonic）州（sneutrino）的under under-e^$ e^$ e^$ e^+e^+e^+e^+e^+e^+e^+e^+e^+e^+e^ 500 GEV。来自Chargino对产生和随后的衰减的新兴信号非常纯净，因此它可以提取（S）中微子部门的Yukawa参数。然后，这些结果应激励在此类加速器上搜索光DM信号，在这种加速器中，可以访问Electro Weak（EW）量表的DM候选者。
We study the possibility of measuring neutrino Yukawa couplings in the Next-to-Minimal Supersymmetric Standard Model with right-handed neutrinos (NMSSMr) when the lightest Supersymmetric partner (a right-handed sneutrino) is the Dark Matter (DM) candidate, by exploiting a `dijet + dilepton + Missing Transverse Energy' (MET) signature. We show that, unlike the miminal realisation of Supersymmetry (SUSY), i.e., the MSSM, for which the DM candidate is a much heavier (fermionic) state (a neutralino), this non-minimal SUSY model offers one with a much lighter (bosonic) state (a sneutrino) as DM, which can be produced at future $e^+e^-$ colliders with energies up to about 500 GeV. The emerging signal, from chargino pair production and subsequent decay, is extremely pure so it allows for the possibility of extracting the Yukawa parameters of the (s)neutrino sector. These results should then motivate searches for light DM signals at such accelerators, where a DM candidate with mass at the Electro-Weak (EW) scale can then be accessed.
