当中微子使一种夸克转化为另一种夸克时，会发射出一个轻子。When a neutrino transforms a quark, a lepton is emitted.

夸克不仅带有重子数、电荷，而且也带有轻子荷。The quarks have not only baryon number and charge but also lepton charge.

除了超对称之外的其它过程也可能导致出现三轻子对结果的出现。Processes other than supersymmetry could also account for the triple lepton surplus.

标准模型中是不存在轻子味破缺过程的，因为中微子没有质量。There is no lepton flavor violating process in the Standard Model, because of the massless neutrino.

在本文中，我们在左右对称模型中研究了轻子混合和轻子生成机制。In this thesis, we study the lepton mixing an-gles and leptogenesis in the left-right symmetric model.

于是在各种新物理模型中，对轻子味破缺过程的研究是一个必要的工作。So the research on the lepton flavor violation processes is a necessary job in a variety of new physical models.

这意味着我们无法通过伴随而生的带电轻子来定义中微子的味量子数，从而导致物理上一致性的矛盾。This means that we cannot define a neutrino flavor by the flavor of associated charged lepton and results in contradictions.

尽管很多属于轻子范畴的粒子名字古怪，如μ子和τ子等，但其中最为人们所熟悉的轻子还是电子。The most familiar lepton is the humble electron, though other, more exotic particles such as muons and taus also fall in this category.
