Query: K-essential Leptogenesis   K-essence is a possible candidate for dark energy of the Universe. In this
paper we consider couplings of k-essence to the matter fields of the standard
electroweak theory and study the effects of the cosmological CPT violation
induced by the CPT violating {\bf Ether} during the evolution of the k-essence
scalar field on the laboratory experiments and baryogenesis. Our results show
that the matter and antimatter asymmetry can be naturally explained {\it via}
leptogenesis without conflicting with the experimental limits on CPT violation
test. The mechanism for baryogenesis proposed in this paper provides a unified
picture for dark energy and baryon matter of our Universe and allows an almost
degenerate neutrino mass pattern with a predicted rate on the neutrinoless
double beta decays accessible to the experimental sensitivity in the near
future.
