论文摘要
尽管LHC在LHC完成了实验完成，但仍需要扩展基本颗粒（SM）的标准模型，但出于各种物理原因，包括冷暗物质（DM）。每个扩展都带有其比例和机制，通常在循环级别上抬起电动尺度朝向其高尺度。问题是要保持静电量表稳定，同时为上述重型扩展提供了空间。为此，事实证明，如果在重量标量的情况下，如果其四分之一的耦合在质量变性时以一定的标度统一，则SM Higgs扇区保持稳定。在这种大规模定位驱动的统一（MDDU）下，发现所关注的标量有资格为可行的DM候选者，并使Electroweak量表保持稳定。我们的详细模拟研究明确表明，MDDU参数空间与当前的对撞机和天体物理界限一致。我们的工作可以扩展到其他相关标量（例如Flavons，Inflaton等），作为一种机制，将Electroweak量表保持稳定。
The standard model of elementary particles (SM), despite experimental completion at the LHC, needs to be extended for various physical reasons, including the cold dark matter (DM). Each extension comes with its scale and mechanism, and typically lifts, at the loop level, the electroweak scale towards its high scale. The problem is to keep the electroweak scale stable while providing a room for the aforementioned heavy extensions. To this end, it turns out that the SM Higgs sector remains stable in the presence of a heavy scalar if their quartic couplings unify at a certain scale when their masses are degenerate. Under this mass-degeneracy-driven unification (MDDU), the scalar under concern is found to qualify as a viable DM candidate and to leave the electroweak scale stable. Our detailed simulation studies explicitly show that the MDDU parameter space agrees with current collider and astrophysical bounds. Our work can be extended to other relevant scalars (like flavons, inflaton and others) as a mechanism by which the electroweak scale is held stable.
