SUPERSYMMETRY BREAKING THROUGH BOUNDARY-CONDITIONS ASSOCIATED WITH THE U(1)(R)

The effects of boundary conditions of the fields for the compactified space directions on the supersymmetric theories are discussed. The bou ndary conditions can be taken to be periodic up to the degrees of free dom of localized U(1)(R) transformations. The boundary condition break s the supersymmery to yield universal soft supersymmetry breaking term s. The 4-dimensional supersymmetric QED with one flavour and the pure supersymmetric QCD are studied as toy models when one of the space coo rdinates is compactified on S-1.
