Abstract

We propose a mechanism that describes an alternative procedure to the direct product of groups by involving some scalar fields related to the group parameters In particular the method may provide a framework for grand unified theories with a minimal increase in the number of fundamental fields requiredМы предлагаем механизм который описывает альтернативную процедуру получения прямого произведения групп посредством включения некоторых скалярных полей связанных с параметрами груии В частности предложенный метод может обеспечить основу для великой единой теории с минимальным увеличением числа требуемых фундаментальных полейSi propone un meccanismo che descrive una procedura alternativa al prodotto diretto di gruppi coinvolgendo campi scalari correlati ai parametri di gruppi In particolare il metodo può fornire una base alla teoria della grande unificazione con un incremento minimo del numero di campi fondamentali richiesto
