Limits on Q-ball size due to gravity
T. Multamaki, I. Vilja
Solitonic scalar field configurations are studied in a theory coupled to gravity. It is found that non-topological solitons, Q-balls, are present in the theory. Properties of gravi…
Simulations of Q-Ball Formation
T. Multamaki, I. Vilja
The fragmentation of the Affleck-Dine condensate is studied by utilizing 3+1 dimensional numerical simulations. The 3+1 dimensional simulations confirm that the fragmentation proce…
Constraints on self-interacting Q-ball dark matter
K. Enqvist, A. Jokinen, T. Multamaki +1
We consider different types of Q-balls as self-interacting dark matter. For the Q-balls to act as the dark matter of the universe they should not evaporate, which requires them to…
Excited Q-Balls in the MSSM with gravity mediated supersymmetry breaking
Tuomas Multamaki
Excited Q-balls are studied by numerical simulations in the Minimal Supersymmetric Standard Model with supersymmetry broken by a gravity mediated mechanism. It is found that there…
Numerical simulations of fragmentation of the Affleck-Dine condensate
K. Enqvist, A. Jokinen, T. Multamaki +1
We present numerical simulations of fragmentation of the Affleck-Dine condensate in two spatial dimensions. We argue analytically that the final state should consist of both Q-ball…
Q-ball collisions in the MSSM: gauge-mediated supersymmetry breaking
Tuomas Multamaki, Iiro Vilja
Collisions of non-topological solitons, Q-balls, are considered in the Minimal Supersymmetric Standard Model where supersymmetry has been broken at a low energy scale via a gauge m…
