AI中文摘要：
LUX-ZEPLIN实验报道的高反冲事件激发了具有亚MeV范围内非弹性劈裂的电弱中性态。我们提出了源自超对称$SU(6)$大统一理论模型的超对称331模型，并研究了与该反冲事件相关的电弱微子（electroweakino）扇区。在331破缺能标之上，超荷并非独立的规范因子，领先的bino-wino抵消被物理$U(1)_X$和$SU(3)_L$规范微子不变量之间的关系$I_X=-I_L$所取代。单态-伴随规范动能项也将色不变量关联起来。我们对可重整化模型的中性规范-希格斯费米子扇区进行对角化，并在不手动引入有效bino质量的情况下确定树级Higgsino劈裂。所需解在规范微子和331破缺参数中形成连续轨迹。在参考点处，解接近领先求和规则，而331破缺耦合的变化使轨迹连续移动。相同的计算检验了额外中性态的顺序、规范/规范微子对331破缺标量质量的贡献以及引力微子顺序。我们将此构造与近期对LZ事件的$SU(5)$、singlino辅助、电弱多重态、核响应和太阳俘获分析进行了比较。
英文摘要：
The high-recoil event reported by LUX--ZEPLIN motivates a neutral electroweak state with an inelastic splitting in the sub-MeV range. We propose supersymmetric 331 model from the supersymmetric $SU(6)$ GUT model, and we study the electroweakino sector relevant to this recoil. Above the $331$-breaking scale hypercharge is not an independent gauge factor, and the leading bino--wino cancellation is replaced by a relation between the physical $U(1)_X$ and $SU(3)_L$ gaugino invariants, $I_X=-I_L$. A singlet--adjoint gauge-kinetic source also correlates the colored invariant. We diagonalize the neutral gauge--Higgs fermion sector of the renormalizable model and determine the tree-level Higgsino splitting without introducing an effective bino mass by hand. The required solutions form a continuous locus in the gaugino and $331$-breaking parameters. At the reference point, the solution lies close to the leading sum rule, while variation of the $331$-breaking coupling moves the locus continuously. The same calculation tests the ordering of the additional neutral states, the gauge/gaugino contribution to the $331$-breaking scalar mass, and the gravitino ordering. We compare this construction with recent $SU(5)$, singlino-assisted, electroweak-multiplet, nuclear-response and solar-capture analyses of the LZ event.
