Cp. Martin et Fr. Ruiz, HIGHER COVARIANT DERIVATIVE PAULI-VILLARS REGULARIZATION DOES NOT LEAD TO A CONSISTENT QCD, Nuclear physics. B, 436(3), 1995, pp. 545-581
We compute the beta function at one loop for Yang-Mills theory using a
s regulator the combination of higher covariant derivatives and Pauli-
Villars determinants proposed by Faddeev and Slavnov. This regularizat
ion prescription has the appealing feature that it is manifestly gauge
invariant and essentially four-dimensional. It happens however that t
he one-loop coefficient in the beta function that it yields is not -11
/3, as it should be, but -23/6. The difference is due to unphysical lo
garithmic radiative corrections generated by the Pauli-Villars determi
nants on which the regularization method is based. This no-go result d
iscards the prescription as a viable gauge invariant regularization, t
hus solving a long-standing open question in the literature. We also o
bserve that the prescription can be modified so as to not generate unp
hysical logarithmic corrections, but at the expense of losing manifest
gauge invariance,
