Summary
The regularization of the one-meson loop in the presence of an external gravitational field by the ’t Hooft-Veltman method is shown to be possible in an Einstein-invariant manner.
Riassunto
Si dimostra che la regolarizzazione dell’ansa di un mesone in presenza di campi gravitazionali esterni col metodo di ’t Hooft-Veltman è possibile in modo einsteiniano invariante.
Реэюме
Покаэывается, что, испольэуя метод Хуфта-Вельтмана, можно зйнщтейновским инвариантным обраэом проиэвести регуляриэацию одно-меэонной петли в присутствии внещнего гравитационного поля.
