Независимый от параметра регуляризации подход в четырехфермионной модели взаимодействия

Независимый от параметра регуляризации подход в четырехфермионной модели взаимодействия

Abstract

В квантовой хромодинамике непертурбативный эффект является неотъемлемым явлением при низких энергиях. Обычная пертурбативность теряет силу. Четырехфермионная модель взаимодействия используется для оценки явления низких энергий для кварков и глюонов. Так как четырехфермионное взаимодействие неперенормируемо, результаты зависят от параметра регуляризации в четырехмерном пространсте-времени. Здесь мы покажем возможность устранения зависимости параметра регуляризации для некоторых физических наблюдений.

In QCD a non-perturbative effect is essential in low energy phenomena. A usual perturbative procedure loses its validity. A four-fermion interaction model is used to evaluate the low energy phenomena for quarks and gluons. Since the four-fermion interaction is nonrenormalizable, the results depend on the regularization parameter in four spacetime dimensions. Here we show the possibility to eliminate the regularization parameter dependence for some of physical observables.
