Varying constants driven baryogenesis
  We study the spontaneous baryogenesis scenario in the early universe for
three different frameworks of varying constants theories. We replace the
constants by dynamical scalar fields playing the role of thermions. We first
obtain the results for baryogenesis driven by the varying gravitational
constant, $G$, as in the previous literature, then challenge the problem for
varying fine structure constant $\alpha$ models as well as for varying speed of
light $c$ models. We show that in each of these frameworks the current
observational value of the baryon to entropy ratio, $\eta_B \sim 8.6 \cdot
10^{-11}$, can be obtained for large set of parameters of dynamical constants
models as well as the decoupling temperature, and the characteristic cut-off
length scale.
