Abstract The Higgs may couple to a topological 4-form sector which yields a complex vacuum structure. In many of the resulting Higgs vacua electroweak symmetry is unbroken. In just as many it breaks when the 4-form flux is large enough. For a fixed value of flux, the symmetry breaking vacua have a smaller vacuum energy than the symmetric ones, where the difference is quantized because it is set by the 4-form flux. This leads to the possibility that there is a value of the 4-form flux for any UV contributions to the Higgs vev that automatically cancels it down to the right value, ∼ TeV, if the 4-form charges are quantized in the units of the electroweak scale. This would still leave the cosmological constant which could be selected anthropically. In addition, the 4-form couplings could lead to direct CP violation in a non-minimal Higgs sector.

摘要 Higgs 可能会耦合到一个拓扑 4 型扇区,从而产生一个复杂的真空结构。在许多由此产生的希格斯真空中,弱电对称性是不间断的。当 4 型通量足够大时,它会断裂。对于固定值的通量,对称破缺真空具有比对称破缺更小的真空能量,其中差异被量化,因为它是由 4 型通量设定的。这导致可能存在任何 UV 对 Higgs vev 贡献的 4 型通量值,该值会自动将其抵消到正确的值,∼ TeV,如果 4 型电荷以弱电秤。这仍然会留下可以人为选择的宇宙常数。此外,4 型耦合可能导致非最小希格斯扇区中的直接 CP 破坏。
