Gauged Q-balls in flat potentials are qualitatively similar to thin-wall versions, with analytic approximations matching numerics and Proca Q-balls interpolating between global and gauged regimes.

abstract
The scalar potential of the Minimal Supersymmetric Standard Model (MSSM) is nearly flat along many directions in field space. We provide a catalog of the flat directions of the renormalizable and supersymmetry-preserving part of the scalar potential of the MSSM, using the correspondence between flat directions and gauge-invariant polynomials of chiral superfields. We then study how these flat directions are lifted by non-renormalizable terms in the superpotential, with special attention given to the subtleties associated with the family index structure. Several flat directions are lifted only by supersymmetry-breaking effects and by supersymmetric terms in the scalar potential of surprisingly high dimensionality.

Spontaneous CP violation is realized in SUSY via an extended spurion formalism in the exact limit and a model with intermediate-scale breaking along pseudo-flat directions stabilized by soft terms and non-perturbative gauge effects, predicting light scalars.
