The effect of Wilson line moduli on CP-violation by soft supersymmetry breaking terms

Abstract

The CP-violating phases in the soft supersymmetry-breaking sector in orbifold compactifications with a continuous Wilson line are investigated. In this case the modular symmetry is the Siegel modular group $Sp(4,Z)$ of genus two. In particular, we study the case that the hidden sector non-perturbative superpotential is determined by the Igusa cusp form ${\mathcal{C}}_{12}$ of modular weight 12. The effect of large non-perturbative corrections to the dilaton Kähler potential on the resulting CP-violating phases is also investigated.
