Scientific paper

In conventional scenarios of baryogenesis it is extremely difficult, if not impossible, to produce local fluctuations in the baryon-to-photon ratio (so-called isocurvature baryon number fluctuations) on sufficiently large scales to be important for structure formation. Using a recently proposed scenario for baryogenesis called ``spontaneous baryogenesis'', we show that isocurvature baryon number fluctuations with the Zel'dovich spectrum and amplitude ~ 10-3 can be produced in inflationary universe models. It is also possible that non-scale invariant baryon number fluctuations could be produced in more complicated inflationary scenarios, and if so might help to revive the baryon-dominated, or neutrino-dominated scenarios of structure formation.
