μ → eγ и другие редкие распады вSU 6 супер-унифицироэа нной калибровочной теории

Il Nuovo Cimento A (1965-1970)

Summary

New interactions, present in the recently proposedSU 6 gauge theory, are discussed. They are related to some rare decays like μ → eγ and \( K_L^0 \to \mu \bar \mu \) . Corrections to anomalous magnetic moments and to theVA theory are also studied. The masses of the bosons responsible for these new interactions could be determined in the case that one observes μ → eγ and/or production of SPEAR 1.9 GeV leptons in neutrino reactions. The model allows for the existence of two neutral currents. The symmetry-breaking mechanism is discussed as well.

Riassunto

Si discutono nuove interazioni presenti nella teoria di gauge della simmetriaSU 6 recentemente proposta. Esse sono correlate ad alcuni decadimenti rari comeμ → eγ e \( K_L^0 \to \mu \bar \mu \). Si studiano anche le correzioni per i momenti magnetici anomali e per la teoriaVA. Le masse dei bosoni responsabili di queste nuove interazioni potrebbero essere determinate nel caso in cui si osservino il decadimentoμ → eγ e/o la produzione di leptoni di 1.9 GeV a SPEAR nelle reazioni di neutrini. Il modello consente l’esistenza di due correnti neutrali. Si discute pure il meccanismo di rottura della simmetria.

Реэюме

Обсуждаются новые вэаимодействия, присутствуюшие в недавно предложеннойSU 6 калибровочной теории. Они свяэаны с некоторыми редкими распадами, подобными μ → eγ и \( K_L^0 \to \mu \bar \mu \). Также исследуются поправки к аномальным магнитным моментам и кVA теории. Массы боэонов, ответственных эа зти новые вэаимодействия, могут быть определены в случае, когда наблюдается μ → eγ и/или обраэование SPEAR 1.9 ГзB лентона в нейтринных реакциях. Предложенная модель допускает сушествование двух нейтральных токов. Также обсуждается механиэм нарущения симметрии.
