Electroweak Baryogenesis and the Expansion Rate of the Universe
A homogeneous mode of a scalar field in a ``fast roll'' ( \dot{\phi}^2 >> V(\phi)), which has an energy density scaling as 1/a^6 in an expanding universe, could dominate the universe at the electroweak epoch. The requirement that the energy in the mode red-shift away before nucleosyn...
