Universal contributions to scalar masses from five dimensional supergravity
Dr. Gero von Gersdorff (CNRS)

Supersymmetric models with a strongly coupled regime at high energy can provide a very convincing theory of flavor. Their phenomenology has been studied by many authors using either purely 4d models (supersymmetric QCD) or 5d descriptions (the supersymmetric Randall Sundrum model).
I will argue that these models generically produce new contributions to soft terms due to the presence of meson resonances of the strongly coupled theory (the Kaluza Klein excitations of the extra dimension).
I will explicitly compute the scalar soft terms in a 5d setup and show that there exist fairly model-independent contributions that are tachyonic, thus putting strong new constraints on model building in these theories.
