Query: Charge Generation in the Oscillating Background   The preheating after the inflation, which can be interpreted as particle
creation in the oscillating inflaton background, provides a state far from
thermal equilibrium. We extend the field theoretical treatment of the
preheating by Linde et al. to the case of multicomponent complex scalars to
show that some charges are created in this process, if C and CP are violated. A
new possibility of baryogenesis based on this mechanism is also discussed.
