质量比参数化

The mass ratios parametrization

Ulises J. Saldana-Salazar, Karla M. Tame-Narvaez

摘要:

观察到的费米子质量的等级,这意味着一组小的质量比,并不是自然的小,根据特胡夫特的标准。在这项工作中,在一个模型独立的方法,我们引入了一组条件,费米子质量比成为自然的。有趣的是,这些条件要求费米子混合应该由每个费米子扇区的四个独立的质量比来描述。将这组条件应用于标准理论,可以使人们理解夸克和轻子混合的主要方面。这一特征可以作为自然界中存在味对称性的有力证据。此外,为了使这种分析在轻子扇区中起作用,中微子质量应该具有正常的顺序,最轻的中微子质量满足下限$m_{ν1} \geqslant (5.0\pm 0.1) \text{ meV}$,使方法可测试。

英文摘要:

The observed hierarchy in the fermion masses, which imply a set of small mass ratios, is not naturally small regarding 't Hooft's criteria. In this work, in a model independent approach, we introduce a set of conditions by which fermion mass ratios become natural. Interestingly, these conditions demand that fermion mixing should be described by the four independent mass ratios of each fermion sector. Application of this set of conditions to the standard theory enables one to understand the mains aspects in quark and lepton mixing. This feature can be taken as a strong evidence for the existence in Nature of a flavour symmetry. Also, for this analysis to work in the lepton sector, neutrino masses should have normal ordering with the lightest neutrino mass satisfying the lower bound, $m_{ν1} \geqslant (5.0\pm 0.1) \text{ meV}$, making the approach testable.
