Query: Flavon Magneto-Baryogenesis   In this paper, we explore the evolution of baryon asymmetry as well as the
hypermagnetic field in the early universe with an assumption that the flavon of
the Froggatt-Nielsen carries an asymmetry. Through the decay of the flavon to
Standard Model fermions, this asymmetry is transferred to fermions, where the
right-handed electron keeps its asymmetry while its Yukawa interaction is out
of thermal equilibrium. Through the existence of the flavon, we can ensure that
the freezing-in temperature of the right-handed electron is closer to the
electroweak phase transition than the Standard cosmology scenario. With this
trick, the asymmetry in the right-handed electron is saved for a longer time.
Moreover, the injection of the asymmetry to the right-handed electron is
gradual, which helps the preservation of the asymmetry in the right-handed
sector significantly. Due to the intimate relationship between fermion number
violation and the helicity of the hypermagnetic field, some of the asymmetry is
used to amplify the hypermagnetic field which itself helps to preserve the
remnant asymmetry through keeping the Yukawa processes out of thermal
equilibrium. We find the sweet region of the parameter space that can produce
the right asymmetry in the baryons while generating a large hypermagnetic field
by the time of the electroweak phase transition.
