Summary
In the Abelian gauge field theory of an axial-vector meson coupled to a conserved axial current, one elaborates a mechanism first proposed by Adler, Gross and Jackiw to compensate the failure of the axial Ward identity by including an extra termO(g 3) in the Lagrangian density. This extra contribution is quantized first in a noncovariant gauge, along with the free-field contribution. A Lorentz-invariant form is then given and spontaneous symmetry breaking is shown to arise in higher orders.
Riassunto
Si elabora il meccanismo, precedentemente proposto da Adler, Gross e Jackiw, nella teoria del campo di gauge abeliano di un mesone vettoriale assiale accoppiato ad una corrente assiale conservata, per compensare il fallimento dell’identità assiale di Ward includendo un termine extraO(g 3) nella densità Lagrangiana. Si quantizza questo contributo extra prima in un gauge non covariante, assieme con il contributo del campo libero. Quindi si dà una forma invariante secondo Lorentz, e si mostra che, all’ordine superiore, si ha una rottura spontanea di simmetria.
Реэюме
В теории абелева калибровочного поля для аксиально-векторного меэона, свяэанного с сохраняюшимся аксиальным током, раэвивается механиэм, впервые предложенный Адлером, Гроссом и Якивом, для устранения недостатков аксиального тождества Уорда, посредством включения дополнительного членаO(g 3) в плотность Лагранжиана. Сначала зтот дополнительный вклад квантуется в нековариантной калибровке вместе с вкладом свободного поля. Затем приво-дится Лорентц-инвариантная форма и покаэывается, что воэникает спонтанное нарущение симметрии в высщих порядках.

The mixing term (A · ∂ϑ) ⋍ −ϑ(∂ · A) appears frequently in the quantization of spin-1 fields (cf.,e.g.,N. Nakanishi:Prog. Theor. Phys.,38, 381 (1971)).
The term ℒ3(x) was included in part of the treatment of sect.2, because it can represent certain radiative corrections. (See,e.g.,E. Lifchitz andL. Pitayevski, Vol.4, p. 150.)
