In a renormalizable gauge theory of sp ontaneously broken symmetry, using the path integral method, we derive a formula for calculating the one loop corrections of the effective potentials in the general case and the expressions for the one loop corrections of the fermion masses. Using this results, we calculate the contributions of the one loop corrections of the fermion masses to the QCD CP-violation, and have obtained a more general results than V. Goffins'. We discuss also the weak CP-violation in...
