✦ Synopsis
Hawking's ('-function regularization method is used to obtain the effective QCD Lagrangian for ordinary quarks moving in some constant background field. The general context is Adler's mean-field approximation to QCD, and an extension of his results is obtained for three particular models. Namely, at one loop order, massive quarks in a constant self-dual, pure colormagnetic, or pure colorelectric field are confined, and this is true for any number of quark flavors. Also, a criterion is established to calculate the values and signs of the imaginary parts for E-and B-lields. The final results for these imaginary parts are in agreement with those of Nielsen and Olesen, and Yildiz and Cox.
