Рассмотрены безмассовые волновые уравнения в формализме ковариантных проекционных операторов спина. Приведены необходимые и достаточные условия калибровочной инвариантности уравнения и ограничения на внешний источник.
The general form of massive superfield equations of motion is proposed, using the formalism of superprojectors. It is shown that the known equations for scalar and bispinor superfield mav be presented in a given general form. The possible equations for a vector superfield and scalar superfield which describe superspin 3 / 2 and lower superspins, are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
