Two-photon decays of scalar and pseudoscalar bosons in supersymmetry

Abstract
We calculate the one-loop contribution to the two-photon decay widths of scalar and pseudoscalar bosons in a supersymmetric SU(2)×U(1) gauge theory using component fields. Effective Lagrangians for these reactions are also constructed using superfields, thus confirming that these widths do not vanish in the supersymmetric limit.
