论文摘要
我们研究了是否可以扩展自私/戈德洛克斯Higgs模型，以使真空吸尘器具有正确的Higgs质量和宇宙学常数。通过引入多个四色场和HIGGS标量玻色子，我们发现宇宙常数和电子层次结构问题都可以同时解决，而无需手动插入相关的物理尺度并避免进行微调。理论的唯一尺寸自由参数在勃雷电荷上的最终界限取决于四形式标量耦合的强度，并且可能与单独通过Bousso-Polchinski机制解决宇宙学恒定问题的解决方案相同。
We investigate whether selfish/Goldilocks Higgs models can be extended to accomodate vacua with both the right Higgs mass and cosmological constant. Through the introduction of multiple four-form fields coupled with the Higgs scalar boson we find that both the cosmological constant and the electroweak hierarchy problems can be addressed simultaneously, without inserting the relevant physical scales by hand and avoiding fine tuning. The resulting bounds on the brane charges, the only dimensionful free parameter of the theory, depend on the strength of the four-form scalar coupling and can be of the same order of magnitude as those necessary for a solution to the cosmological constant problem alone via the Bousso-Polchinski mechanism.
