Minimal coupling and unitarity: a comment on a model of massive Yang-Mills fields proposed by ’t Hooft and Veltman

Минимальная свяэь и унитарность: Замечание о модели массивных полей Янга-Миллса, предложенной Хофтом и Велтманом

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

Summary

A model proposed by ’t Hooft and Veltman shows that a theory of massive Yang-Mills field is possible if the hypothesis of minimal coupling is released. We derive the model by using the Slavnov transformations, without using the Higgs mechanism. We briefly discuss the zero-mass limit.

Riassunto

Un modello proposto da ’t Hooft e Veltman mostra che una teoria di Yang e Mills massiva è possibile se si abbandona l’ipotesi di accoppiamento minimo. Si deriva la Lagrangiana usando le trasformazioni di Slavnov, senza fare uso del meccanismo di Higgs. Si discute brevemente il limite di massa nulla.

Реэюме

Модель, предложенная Хофтом и Велтманом, покаэывает, что теория массивного поля Янга-Миллса является воэможной, если реалиэуется гипотеэа минимальной свяэи. Мы предлагаем модель испольэуя преобраэования Славнова, но не испольэуя механиэм Хиггса. Вкратце обсуждается предел нулевой массы.
