Neutral currents in unified gauge models

Нейтральные токи в единых калибровочных моделях

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

Theq 2-dependence of the effective neutral-current Hamiltonian for lowest-order weak processes is investigated by generalizing the formalism introduced by Georgi and Weinberg. The method is applied to left-right-symmetric gauge models based on the groups\(\bar G_{LR} \equiv SU_{2L} \times SU_{2R} \times U_{1L + R} \) andG LRSU 2L×SU 2R×U 1L×U 1R.

Riassunto

Generalizzando il formalismo introdotto da Georgi e Weinberg, si esamina la dipendenza inq 2 dell’Hamiltoniano effettivo delle correnti neutre deboli all’ordine più basso. Il metodo è applicato a modelli di gauge ambidestri, basati sui gruppi\(\bar G_{LR} \equiv SU_{2L} \times SU_{2R} \times U_{1L + R} \) eG LRSU 2L×SU 2R×U 1L×U 1R.

Резюме

Исслэдуетсяq 2-зависимость эффективного Гамильтониана нейгральных токов для слабых процессов ниэшего порядка, обобщая формализм, введенный Джорджи и и Вейнбергом. Предложенный метод применяется к калибровочным моделям, основанным. Предложенный метод прнменгется к калибровочным моделям, основанным на группах\(\bar G_{LR} \equiv SU_{2L} \times SU_{2R} \times U_{1L + R} \) иG LRSU 2L×SU 2R×U 1L×U 1R.
