Two-loop renormalization group equations in gauge theories with multiple U(1)
groups are presented. Instead of normalizing the abelian gauge fields in
canonical forms, we retain kinetic-mixing terms and treat the mixing
coefficients as free parameters. The beta- and gamma-functions are then
obtained in a straightforward manner.
