Query: The Electroweak Axion, Dark Energy, Inflation and Baryonic Matter   In a previous paper, the standard model was generalized to include an
electroweak axion which carries baryon plus lepton number, $B+L$. It was shown
that such a model naturally gives the observed value of the dark energy, if the
scale of explicit baryon number violation was chosen to be of the order of the
Planck mass. In this paper, we consider the effect of the modulus of the axion
field. Such a field must condense in order to generate the standard Goldstone
boson associated with the phase of the axion field. This condensation breaks
baryon number. We argue that this modulus might be associated with inflation.
If an additional $B-L$ violating scalar is introduced with a mass similar to
that of the modulus of the axion field, we argue that decays of particles
associated with this field might generate an acceptable baryon asymmetry.
