关于Higgsplosion

Problems with Higgsplosion

Alexander Belyaev, Fedor Bezrukov, Chris Shepherd, Douglas Ross

摘要:

最近对具有自发对称性破缺的标量理论中的多希格斯玻色子产生的计算表明,在足够大的能量下,具有希格斯多重性的截面快速增长,称为“希格斯爆炸”。有人认为,“希格斯爆炸”解决了希格斯层次和微调问题。本文认为:(1)“希格斯爆炸”公式的适用性有限,与标准模型的幺正性不一致;(2)“希格斯爆炸”对希格斯玻色子传播子虚部的贡献不能重新求和,从而不能提供希格斯层次和微调问题的解决方案。

英文摘要:

A recent calculation of the multi-Higgs boson production in scalar theories with spontaneous symmetry breaking has demonstrated the fast growth of the cross section with the Higgs multiplicity at sufficiently large energies, called "Higgsplosion". It was argued that "Higgsplosion" solves the Higgs hierarchy and fine-tuning problems. In our paper we argue that: a) the formula for "Higgsplosion" has a limited applicability and inconsistent with unitarity of the Standard Model; b) that the contribution from "Higgsplosion" to the imaginary part of the Higgs boson propagator cannot be re-summed in order to furnish a solution of the Higgs hierarchy and fine-tuning problems.
