准相对论费米子和动力学味振荡

Quasi-relativistic fermions and dynamical flavour oscillations

Jean Alexandre, Julio Leite, Nick E. Mavromatos

摘要:

我们引入新的洛伦兹对称破坏运动学的四费米子相互作用模型,其中动态质量的产生是允许的,不管耦合的强度。此外,这些运动学导致准相对论色散关系,在这个意义上,它是相对论的红外和紫外线,但不是在中间制度,其特征在于质量$M$。对于两个费米子,我们表明,味道混合质量矩阵动态生成,和洛伦兹对称极限$M\to\infty$导致两个自由相对论费米子,味道振荡。这个模型,无论是狄拉克或马约拉纳费米子有效,可以描述任何一组本征质量和混合角的唯象值。

英文摘要:

We introduce new Lorentz-symmetry violating kinematics for a four-fermion interaction model, where dynamical mass generation is allowed, irrespectively of the strength of the coupling. In addition, these kinematics lead to a quasi-relativistic dispersion relation, in the sense that it is relativistic in both the infrared and the ultraviolet, but not in an intermediate regime, characterized by the mass $M$. For two fermions, we show that a flavour-mixing mass matrix is generated dynamically, and the Lorentz symmetric limit $M\to\infty$ leads to two free relativistic fermions, with flavour oscillations. This model, valid for either Dirac or Majorana fermions, can describe any set of phenomenological values for the eigen masses and the mixing angle.
