We consider the Resonance Chiral Theory with one multiplet of scalar andpseudoscalar resonances, up to bilinear couplings in the resonance fields, andevaluate its beta-function at one-loop with the use of the background fieldmethod. Thus we also provide the full set of operators that renormalize thetheory at one loop and render it finite.Comment: 37 pages, 2 figure
