One-Loop Effects in Supergravity Models with an Additional U(1)

Abstract

For an Abelian extended Supergravity model, we investigate some important low energy parameters: \tanβ, Z-Z' mixing angle, lightest CP-even Higgs mass bound, Z' mass, and effective μparameter. By integrating the RGE's from string scale down to the weak scale we constuct the scalar potential, and analyze the quantities above at the tree- and one-loop levels by including the contributions of top squarks and top quark in the effective potential.
