Infinite Renormalization of Theta-Term and Jarlskog Invariant for CP-Violation

Abstract

The logarithmic ultraviolet divergence in the theta-term induced by electroweak interactions in the Kobayashi-Maskawa model of CP-violation, found by Ellis and Gaillard, is discussed. We relate it to the Jarlskog CP-odd invariant of quark mass matrix. The divergence arises in 14th order in Higgs coupling as well as in 12th order plus 2nd order in U(1) gauge boson coupling.Comment: 6 pages + 1 figure (included), LaTex, TPI-MINN-93/91-T, UMN-TH-1212/9
