Abstract

The saturation of the commutation relations of the space components of the axial currents with multiplets ofSU3×SU2W is considered taking into account possible Schwinger terms It is shown that the saturation with the states of the56+ multiplet is not consistent with a momentum transfer dependence This dependence can be obtained without a renormalization of the staticSU6 results by adding to the56+ a negativeparity multiplet Even without specifying this multiplet we can obtain the results 〈r n 2 〉=0 andD/F=3/2 up to first order in the momentum transferРассматривается насыщение коммутационных соотношений для пространственных компонент аксиальных токов с мультиплетамиSU3×SU2W принимая во внимание возможные члены Швингера Показано что насыщение посредством состояний мультиплета56+ является несовместимым с зависимостью от передаваемого импульса Эта зависимость может быть получена путем добавления к56+ мультиплета с отрицательной четностью без перенормировки результатов статическойSU6 Даже не конкретизируя этот мультиплет мы можем получить результаты 〈r n 2 〉=0 иD/F=3/2 которые справедливы вплоть до первого порядка по передаваемому импульсуViene considerata la saturazione delle relazioni di commutazione delle componenti spaziali delle correnti assiali locali mediante multipletti del gruppo collineareSU3×SU2W Viene mostrato che la saturazione mediante stati della56+ non è consistente con una dipendenza dal trasferimento dimpulso Si può ottenere tale dipendenza senza rinormalizzare i risultati della simmetriaSU6 aggiungendo alla56+ un multipletto a parità negativa Senza specificare tale multipletto è possibile ottenere i risultati 〈r n 2 〉=0D/F=3/2 fino al primo ordine nel trasferimento dimpulso
