论文摘要
我们提出了一种新的机制,可以在通货膨胀期间动态选择电子量表。类似轴的字段$ ϕ $,该$ ϕ $与希格斯的临界点$ ϕ_c $相对较大,在Higgs变得无质量。当$ ϕ $越过这一点时,它进入了Higgs质量为速度的区域,这导致了希格斯颗粒的爆炸性产生。因此,产生了反反应电位,并且场$ ϕ $被吸引到$ ϕ_c $。在这一点左右发生了一系列振荡之后,由于潜力的周期性术语,它最终被困在附近。该模型避免了移植现场的偏移,需要极少的电子通货膨胀,并且与通货膨胀率最高$ 10^5〜 \ rm GEV $兼容。 $ ϕ $的质量位于数百GEV到几个TEV的范围内,并且可以在未来的山脉中进行探测。
We propose a new mechanism to dynamically select the electroweak scale during inflation. An axion-like field $ϕ$ that couples quadratically to the Higgs with a large initial velocity towards a critical point $ϕ_c$ where the Higgs becomes massless. When $ϕ$ crosses this point, it enters a region where the Higgs mass is tachyonic and this results into an explosive production of Higgs particles. Consequently, a back-reaction potential is generated and the field $ϕ$ is attracted back to $ϕ_c$. After a series of oscillations around this point it is eventually trapped in its vicinity due to the periodic term of the potential. The model avoids transplanckian field excursions, requires very few e-folds of inflation and it is compatible with inflation scales up to $10^5~\rm GeV$. The mass of $ϕ$ lies in the range of hundreds of GeV to a few TeV and it can be potentially probed in future colliders.
