Vacuum Stability in Supersymmetric Effective Theories

The main topics discussed in this thesis are supersymmetric low-energy effective theories and metastability conditions in generic non-renormalizable models with global and local supersymmetry. In the first part we discuss the conditions under which the low ...

Effects of heavy modes on vacuum stability in supersymmetric theories

Claudio Scrucca, Leonardo Brizi

We study the effects induced by heavy fields on the masses of light fields in supersymmetric theories, under the assumption that the heavy mass scale is much higher than the supersymmetry breaking scale. We show that the square-masses of light scalar field ...

The lightest scalar in theories with broken supersymmetry

Claudio Scrucca, Leonardo Brizi

We study the scalar mass matrix of general supersymmetric theories with local gauge symmetries, and derive an absolute upper bound on the lightest scalar mass. This bound can be saturated by suitably tuning the superpotential, and its positivity therefore ...
