Renormalization of the electromagnetic current in a non-Abelian gauge theory of strong interactions

  • K. Fabricius
  • I. Schmitt


For a model possibly useful for the description of low-energy hadronic-scattering amplitudes and electromagnetic form factors we construct the electromagnetic current and discuss its Ward identity and renormalization. We find that the unrenormalized current is finite in the physical sector of the Hilbert space.

Перенормнировка электромагнитного тока в неабелевой калибровочной теории силяных взаимодействий


В рамках модели для описания амплитуд рассеяния адронов при низких энергиях и электромагнитных форм-факторов мы конструируем электромагнитный ток и обсуждаем тождество Уорда и перенормировку электромагнитныго тока. Мы получаем, что неперенормированный ток является конечным в физическом секторе гильбертова пространства.


Per un modello possibilmente utile per la descrizione di ampiezze di scattering adronici a bassa energia e fattori di forma elettromagnetici, si costruisce la corrente elettro-magnetica e si discutono la sua identità di Ward e renormalizzazione. Si trova che la sua corrente di non renormalizzazione è finita nel settore fisico dello spazio di Hilbert.
