论文摘要
我们测试了$ e_6 $实现通用$ u（1）'$扩展最小超对称标准模型（UMSSM），以与新的$ u（1）'$ u（1）'$ u（1）'$θ_{e_6} $有关的混合角度进行参数，从空间到地面实验，从高点到高效。我们发现实验约束非常限制，并表明在此理论构造中需要大量的量规动力学混合和$θ_{e_6} \ of -y -y -out -out -out -y -π/3 $，以实现符合当前数据的依从性。后果是双重的。一方面，大量量规动力学混合意味着，$ z'$玻色子从额外的$ u（1）'$对称性的破裂中出现，因为它主要腐烂成$ ww $ pairs。另一方面，首选的$θ_{e_6} $ value呼叫与相当特定的$ e_6 $打破模式不同于常见研究的模式。最终，我们在大型强子对撞机（LHC）和暗物质（DM）实验中描述了新兴的UMSSM场景的潜在特征。
We test $E_6$ realisations of a generic $U(1)'$ extended Minimal Supersymmetric Standard Model (UMSSM), parametrised in terms of the mixing angle pertaining to the new $U(1)'$ sector, $θ_{E_6}$, against all currently available data, from space to ground experiments, from low to high energies. We find that experimental constraints are very restrictive and indicate that large gauge kinetic mixing and $θ_{E_6}\approx -π/3$ are required within this theoretical construct to achieve compliance with current data. The consequences are twofold. On the one hand, large gauge kinetic mixing implies that the $Z'$ boson emerging from the breaking of the additional $U(1)'$ symmetry is rather wide since it decays mainly into $WW$ pairs. On the other hand, the preferred $θ_{E_6}$ value calls for a rather specific $E_6$ breaking pattern different from those commonly studied. We finally delineate potential signatures of the emerging UMSSM scenario in both Large Hadron Collider (LHC) and in Dark Matter (DM) experiments.
