Radion Induced Spontaneous Baryogenesis
We describe a possible scenario for the baryogenesis arising when matter is added on the branes of a Randall-Sundrum model with a radion stabilizing potential. We show that the radion field can naturally induce spontaneous baryogenesis when the cosmological evolution for the matter on the branes is taken into account.
متن کاملSpontaneous Baryogenesis in Supersymmetric Models
Abstract In this paper we extend the results of previous work on spontaneous baryogenesis to general models involving CP violation in the Higgs sector. We show how to deal with Chern-Simons terms appearing in the effective potential arising from phase changes in the vacuum expectation values of the Higgs fields. In particular, this enables us to apply this mechanism to general supersymmetric mo...
متن کاملSpontaneous baryogenesis in warm inflation
We discuss spontaneous baryogenesis in the warm inflation scenario. In contrast with standard inflation models, radiation always exists in the warm inflation scenario, and the inflaton must be directly coupled to it. Also, the transition to the post-inflationary radiation dominated phase is smooth and the entropy is not significantly increased at the end of the period of inflation. In addition,...
متن کاملForeground Detection with Non-stationary Background
Background subtraction is a traditional technique for finding moving objects (foreground). With a non-stationary viewing sensor, this approach usually assumes that the motion compensation for the background must be sufficiently accurate. In practice, it is difficult to realized this assumption and the background subtraction algorithm will fail for a moving scene. The problem is further compound...
متن کاملA Note on Spontaneous Baryogenesis
The original calculation of ‘spontaneous’ baryogenesis overlooked the role played by transport of particles onto the bubbles wall. For typical ‘adiabatic’ wall thicknesses and velocities one can model the problem in a fluid approximation and the mechanism is best understood as another limit of ‘charge transport’ baryogenesis, and can produce a similar non-local effect in front of the wall. In t...
