Softness of Brane-localized Supersymmetry Breaking on Orbifolds
We consider the brane-localized supersymmetry breaking in 5D compactified on S/Z2. In case of a bulk gaugino with arbitrary brane masses for its even and odd modes, we find the mass spectrum and the wave functions of gaugino. We show that the gaugino masses at the distant brane are soft in the usual sense in the effective field theory with zero modes of bulk gauge fields and they are also extre...
متن کاملBrane - assisted Scherk - Schwarz supersymmetry breaking in orbifolds ∗
We have analyzed the interplay between Scherk-Schwarz supersymmetry breaking and general fermion (gaugino or gravitino) mass terms localized on the fixed point branes of the S/Z2 orbifold. Analytic solutions for eigenfunctions and eigenvalues are found in all cases. All results are checked by numerical calculations that make use of regularized δ-functions. Odd and generically also even fermions...

We consider supersymmetry breaking due to a Scherk-Schwarz twist or localized mass terms in 6d N = 1 supersymmetric gauge theory compactified on the orbifold T /Z2. We show that the Scherk-Schwarz breaking in 6d is equivalent to the localized breaking with mass terms along the lines in extra dimensions. In the presence of the considered supersymmetry breaking, we find that there arises a finite...
متن کاملSupersymmetry breaking on orbifolds from Wilson lines ∗
We consider five dimensional theories compactified on the orbifold S 1 /Z 2 and prove that spontaneous local supersymmetry breaking by Wilson lines and by the Scherk-Schwarz mechanism are equivalent. Wilson breaking is triggered by the SU (2) R symmetry which is gauged in off-shell N = 2 supergravity by auxiliary fields. The super-Higgs mechanism disposes of the would-be Goldstinos which are ab...
متن کاملSoftness of Scherk-Schwarz Supersymmetry Breaking
We investigate how the mass correction appears in 5-D with Scherk-Schwarz compactification and clarify whether the KK regularization is reliable method or not. In the extremely sharp cutoff limit of the 5-D regulator which preserves 5-D Lorentz invariance, we prove that the one loop correction to the mass does not depend on the ultraviolet physics for the Scherk-Schwarz breaking of supersymmetr...
