A model of inhomogeneous baryogenesis based on the Affleck and Dine mechanism
is described. A simple coupling of the scalar baryon field to the inflaton
allows for formation of astronomically significant bubbles with a large baryon
(or antibaryon) asymmetry. During the farther evolution these domains form
compact stellar-like objects, or lower density clouds, or primordial black
holes of different size. According to the scenario, such high baryonic number
objects occupy relatively small fraction of space but despite that they may
significantly contribute to the cosmological mass density. For some values of
parameters the model allows the possibility the whole dark matter in the
universe to be baryonic. Furthermore, the model allows the existence of the
antibaryonic B-bubbles, i.e. a significant fraction of the mass density in the
universe can be in the form of the compact antimatter objects (e.g.
anti-stars).Comment: 31 pages, 5 figures, three references are adde
