Hybridized Affleck-Dine baryogenesis
We propose a novel scenario for Affleck-Dine baryogenesis in the braneworld, considering the hybrid potential for the Affleck-Dine field. Destabilization of the flat direction is not due to the Hubble parameter, but is induced by a trigger field. The moduli for the brane distance plays the role of the trigger field. Q-balls are unstable in models with large extra dimensions.
متن کاملudd-Based Affleck-Dine Baryogenesis
We consider the possibility of a successful Affleck-Dine mechanism along the udd direction in R-parity symmetric extensions of the minimal supersymmetric Standard Model (MSSM) which contain a gauge singlet superfield φ. Such gauge singlets commonly occur in extensions of the MSSM, for example in models which seek to account for neutrino masses. We consider a two scalar Affleck-Dine mechanism, w...
متن کاملAffleck-Dine baryogenesis in the local domain
For Affleck-Dine baryogenesis to proceed, there must have been two types of phase transitions. One is the destabilized-stabilized phase transition of the flat direction, which is in general induced by the Hubble parameter. The other is the phase transition related to the A-term, which induces the misalignment of the relative phase of the flat direction. In the conventional Affleck-Dine baryogen...
متن کاملTowards the robustness of the Affleck-Dine baryogenesis
We study the Affleck-Dine mechanism with various types of the Kähler potential, and investigate whether or not the Affleck-Dine field could acquire a large VEV as an initial condition for successful baryogenesis. In addition to a negative Hubble-induced mass term, we find that large enough Hubble-induced A-terms could also develop the minimum at large amplitude of the field. Therefore, the Affl...
متن کاملAffleck-Dine baryogenesis in large extra dimensions
Baryogenesis in models in which the fundamental scale is as low as 1 TeV in the context of large extra dimensions is a challenging problem. The requirement for the departure from thermal equilibrium necessarily ties any low-scale baryogenesis with that of a successful inflationary model, which automatically provides the out-of-equilibrium condition after the end of inflation. However, it is als...
