摘要:

我们研究的参数的标准模型的扩展。中微子扇区被一个右手单线场扩大,允许跷跷板机制I型,希格斯扇区包含一个额外的双线,通过单圈辐射修正贡献轻中微子质量。采用近似的有效轻中微子质量矩阵,我们表示轻中微子的质量解析,使我们能够参数化的汤川耦合中微子的中微子部门和只有两个自由参数的实验测量。我们专注于CP守恒的希格斯势,我们提出的输入参数的允许范围和统计概述的汤川耦合的可能值。

英文摘要:

We study parameters of an extension of the Standard Model. The neutrino sector is enlarged by one right-handed singlet field, allowing for the seesaw mechanism type-I, and the Higgs sector contains one additional doublet, which contributes to light neutrino masses through one-loop radiative corrections. Employing an approximation for the effective light neutrino mass matrix we express the masses of the light neutrinos analytically, allowing us to parametrize the Yukawa couplings to neutrinos by the experimental measurements on the neutrino sector and only two free parameters. We focus on a CP-conserving Higgs potential for which we present the allowed ranges of the input parameters and a statistical overview over the possible values of the Yukawa couplings.
