希格斯粒子的能量值

Likely values of the Higgs vev

John F. Donoghue, Koushik Dutta, Andreas Ross, Max Tegmark

摘要:

我们对希格斯真空期望值的似然函数进行了估计,通过对原子的存在施加人择约束,同时允许标准模型的其他参数也是可变的。我们认为,最重要的额外成分是汤川耦合,和汤川耦合的内在分布,我们使用的尺度不变分布,这是有利于现象。结果是成功的现象,有利于接近观察到的vev值。我们还讨论了可能改变这些结论的修改。我们的工作支持了这一假设,即人择约束可能是起源的小值的希格斯粒子。

英文摘要:

We make an estimate of the likelihood function for the Higgs vacuum expectation value by imposing anthropic constraints on the existence of atoms while allowing the other parameters of the Standard Model to also be variable. We argue that the most important extra ingredients are the Yukawa couplings, and for the intrinsic distribution of Yukawa couplings we use the scale invariant distribution which is favored phenomenologically. The result is successful phenomenologically, favoring values close to the observed vev. We also discuss modifications that could change these conclusions. Our work supports the hypothesis that the anthropic constraints could be the origin of the small value of the Higgs vev.
