暴胀导致的标准模型希格斯玻色子质量

Standard Model Higgs boson mass from inflation

Fedor L. Bezrukov, Amaury Magnin, Mikhail Shaposhnikov

摘要:

我们分析了理论中对暴胀势的单圈辐射修正,其中暴胀由标准模型希格斯场驱动。我们证明了当Higgs质量m_H处于m_min<m_H<m_max区间时,暴胀是可能的,其中m_min=[136.7+(m_t-171.2)*1.95]GeV,m_max=[184.5+(m_t-171.2)*0.5]GeV,m_t是顶夸克的质量.此外,标量涨落谱指数和张量标量比的预言实际上不依赖于可接纳区内的Higgs质量,相应地等于ns =0.97和r=0.0034。

英文摘要:

We analyse one-loop radiative corrections to the inflationary potential in the theory, where inflation is driven by the Standard Model Higgs field. We show that inflation is possible provided the Higgs mass m_H lies in the interval m_min<m_H<m_max, where m_min=[136.7+(m_t-171.2)*1.95]GeV, m_max=[184.5+(m_t-171.2)*0.5]GeV and m_t is the mass of the top quark. Moreover, the predictions of the spectral index of scalar fluctuations and of the tensor-to-scalar ratio practically do not depend on the Higgs mass within the admitted region and are equal to n_s=0.97 and r=0.0034 correspondingly.
