We show that Q-balls naturally exist in the Minimal Supersymmetric Standard Model (MSSM) with soft SUSY breaking terms of the minimal N=1 SUGRA type. These are associated with the F- and D-flat directions of the scalar potential once radiative corrections are taken into account. We consider two distinct cases, corresponding to the "H_u L" (slepton) direction with L-balls and the "udd" and "uude" (squark) directions with B-balls. The L-ball always has a small charge, typically of the order of 1000, whilst the B-ball can have an arbitrarily large charge, which, when created cosmologically by the collapse of an unstable Affleck-Dine condensate, is likely to be greater that 10^14. The B-balls typically decay at temperatures less than that of the electroweak phase transition, leading to a novel version of Affleck-Dine baryogenesis, in which the B asymmetry comes from Q-ball decay rather than condensate decay. This mechanism can work even in the presence of additional L violating interactions or B-L conservation, which would rule out conventional Affleck-Dine baryogenesis.

Early-Time Nonlinear Growth in an Unstable Q-Ball Hairy Black Hole
The early growth of the weakly responding scalar component in an unstable Q-ball hairy black hole is dominated by a second-order QNM sourced by the linear unstable mode, even while evolution remains perturbative.

Reviving the Affleck-Dine Curvaton Scenario with Compensated Isocurvature Perturbations
The Affleck-Dine field can act as both baryogenesis engine and curvaton if gravitino dark matter, produced before curvaton decay, supplies the compensating isocurvature perturbation that hides the baryon isocurvature ...

Quantum-Corrected Q-balls in the Friedberg-Lee-Sirlin Model
Hartree quantum fluctuations in 3+1D simulations of the Friedberg-Lee-Sirlin model produce a regime where fluctuations carry significant Noether charge, periodic charge exchange occurs, and some classically stable Q-b...

Hydrodynamic properties in soliton field theory
Soliton formation in complex scalar field theory is framed as sound-mode-induced phase separation, and cylindrical Q-strings are shown to suffer a Rayleigh-Plateau membrane instability that breaks them into spheres.
