We use the general formalism of squeezed rotated states to calculate baryon asymmetry in the wake of inflation through parametric amplification. We base our analysis on a B and CP violating Lagrangian in an isotropically expanding universe. The B and CP violating terms originate from the coupling of complex fields with non-zero baryon number to a complex background inflaton field. We show that ...

Phi meson production in heavy-ion collisions at subthreshold energies is studied in the relativistic transport model. We include contributions from the baryon-baryon, pion-baryon, and kaon-antikaon interactions and find that the reaction πN → φN is most important for phi meson production. The implication of our results is discussed with respect to the preliminary experimental data from the FOPI...

I describe a new way for baryogenesis to proceed, which evades many of the problems of GUT and electroweak scenarios. If the reheat temperature after inflation is below the electroweak scale, neither GUT baryon production nor traditional electroweak baryogenesis can occur. However, non-thermal production of sphaleron configurations via preheating could generate the observed baryon asymmetry of ...

The nonlinear evolution of a system consisting of collisional baryons and collisionless dark matter is generally characterized by strong shocks and discontinuities in the baryon fluid. The baryons slow down significantly at postshock areas of gravitational strong shocks, which can occur in high overdense as well as low overdense regions. On the other hand, the shocks do not affect the collapse ...

The statistical production of antibaryons is considered within the canonical ensemble formulation. We demonstrate that the antibaryon suppression in small systems due to the exact baryon number conservation is rather different in the baryon–free (B = 0) and baryon–rich (B ≥ 2) systems. At constant values of temperature and baryon density in the baryon–rich systems the density of the produced an...
