Conformal Supersymmetry Breaking and Dynamical Tuningof the Cosmological Constant

PDF Version Also Available for Download.

Description

We propose 'conformal supersymmetry breaking' models, which tightly relate the conformal breaking scale (i.e. R-symmetry breaking scale) and the supersymmetry breaking scale. The both scales are originated from the constant term in the superpotential through the common source of the R-symmetry breaking. We show that dynamical tuning between those mass scales significantly reduces the degree of fine-tuning necessary for generating the almost vanishing cosmological constant.
