一般轻子质量矩阵与中微子振荡

Generic lepton mass matrices and neutrino oscillations

Rohit Verma

摘要:

本文从一般的角度讨论了中微子振荡现象学的几个有趣的方面,如小中微子质量的起源,中微子的绝对质量标度,中微子的质量等级,即正常的或倒置的,以及中微子的性质,即Dirac或Majorana等。我们展示了如何从幺正变换、自然性和跷跷板机制的基本考虑来确定费米子汤川耦合的织构结构,并讨论了0νββ衰变中的有效质量对这些耦合的织构结构的重要性。

英文摘要:

Several intriguing aspects of neutrino oscillation phenomenology like the origin of small neutrino masses, the absolute neutrino mass scale, the neutrino mass hierarchy, i.e. normal or inverted and the nature of neutrinos, i.e. Dirac or Majorana, etc. have been addressed from a general perspective. We show how the fundamental considerations of unitary transformations, naturalness and seesaw mechanism suffices to determine the texture structure of fermion Yukawa couplings and discuss the significance of the effective mass in 0νββ decay for the texture structure of these couplings.
