Abstract
By assuming that (v e, e−) and (μ+, νμ) belong to the spinor representations θ1/2, 0 and θ0, 1/2 of the rotation group of SU(2)×SU(2), the selection rules for isospin τ and hypercharge s pin ζ are formulated for the pure leptonic processes. As a result, self-current processes such as
belong to the allowed transition, while μ—e exchange processes such as
belong to the forbidden transition.
Leptonic bosons are introduced which are responsible for the mediation of the pure leptonic processes, and their masses and coupling constants are inferred:M L≅130 BeV∼200 BeV,

Резюме
Сформулированы правила отбора для изоспина и гиперзарядового спина з для чисто лептонных процессов при предположении, что (μ+, νμ) и (v e, e−) принадлежат к спинорным представлениям θ1/2,0 и θ0, 1/2 групп вращения SU(2)×SU(2). Из них следует, что в то время как процессы обмена μ-e, такие как
принадлежат к запрещенным переходам, процессы с μ-e собственным током, такие как
принадлежат к разрешенным переходам.
Введены лептонные бозоны, благодаря которым происходит передача чисто лептонных процессов, определены их массы и коэффициенты связи.M L≅130 BeV ∼200 BeV,
