Abstract

We discuss the on-shell N=1 Supersymmetric coupling of brane chiral multiplets in the context of N=2, D=5 Supergravity compactified on $S_{1} / Z_{2}$ orbifolds. Assuming a constant superpotential on the hidden brane we study the transmission of the supersymmetry breaking to the visible brane. We find that to lowest order in the five dimensional Newton's constant $k_{5}^{2}$ and gravitino mass $m_{3/2}^{2}$ the spinor field of the radion multiplet is responsible of inducing positive one-loop squared masses $m_{ϕ}^{2} \sim m_{3/2}^{2} / (M_{P l an c k}^{2} R^{2})$ to the scalar fields which are localized on the visible brane with $R$ the length scale of the fifth dimension. Considering a cubic superpotential on the visible brane we also find that non-vanishing soft trilinear scalar couplings $A$ are induced given by $A = 3 m_{ϕ}^{2} / m_{3/2}$ .
