II型Higgs二重态跷跷板机制与新物理的尺度

Type II seesaw mechanism for Higgs doublets and the scale of new physics

W. Grimus, L. Lavoura, B. Radovcic

摘要:

我们详细阐述了早期的建议欧内斯特马的第二类跷跷板机制抑制一些希格斯双重的真空期望值。我们强调,通过将这种形式的跷跷板机制嵌套到各种其他的跷跷板机制中,人们可以以这样一种方式获得轻中微子质量,即跷跷板机制中存在的新物理尺度--标量规范SU(2)三线态、标量SU(2)双线态或右手中微子的质量--不需要高于几个10 TeV。我们还调查了其他用途的第二类跷跷板机制的希格斯二重态。例如,对Higgs二重态真空期望值的抑制可以在费米子质量矩阵的某些项中实现Froggatt-Nielsen抑制因子。

英文摘要:

We elaborate on an earlier proposal by Ernest Ma of a type II seesaw mechanism for suppressing the vacuum expectation values of some Higgs doublets. We emphasize that, by nesting this form of seesaw mechanism into various other seesaw mechanisms, one may obtain light neutrino masses in such a way that the new-physics scale present in the seesaw mechanism - the masses of scalar gauge-SU(2) triplets, scalar SU(2) doublets, or right-handed neutrinos - does not need to be higher than a few 10 TeV. We also investigate other usages of the type II seesaw mechanism for Higgs doublets. For instance, the suppression of the vacuum expectation values of Higgs doublets may realize Froggatt-Nielsen suppression factors in some entries of the fermion mass matrices.
