Supersymmetric Q-balls and boson stars in (d+1) dimensions

Understand

We construct supersymmetric Q-balls and boson stars in (d+1) dimensions.

• These non-topological solitons are solutions of a scalar field model with global U(1) symmetry and a scalar field potential that appears in gauge-mediated supersymmetry (SUSY) breaking in the minimal supersymmetric extension of the Standard Model (MSSM).
• We are interested in both the asymptotically flat as well as in the asymptotically Anti-de Sitter (AdS) solutions.
• In particular, we show that for our choice of the potential gravitating, asymptotically flat boson stars exist in (2+1) dimensions.
