| Abstract: | We show that no radiative masses are acquired by the Goldstone pion supermultiplet in supersymmetric QCD. Thus, in contrast to ordinary QCD, the mass difference mπ2+?mπ20 remains zero even after electromagnetism is turned on. Bound state Goldstone supermultiplets obey a nonrenormalization theorem analogous to that obeyed by elementary chiral superfields. |
