We calculate Yukawa interactions at one-loop on intersecting D6 branes. Wedemonstrate the non-renormalization theorem in supersymmetric configurations,and show how Yukawa beta functions may be extracted. In addition to the usuallogarithmic running, we find the power-law dependence on the infra-red cut-offassociated with Kaluza-Klein modes. Our results may also be used to evaluatecoupling renormalization in non-supersymmetric cases.Comment: 48 pages, 9 figures; minor corrections, JHEP styl
