We show how thermal leptogenesis induced by the CP-violating decay of a right-handed neutrino (RHN) can be compatible to the assumption of quintessential kination,
i.e.,
to a cosmological background model where the energy density of the early Universe is assumed to be dominated by the kinetic term of a quintessence field during some epoch of its evolution.
The phenomenology depends on the temperature T_r above which kination dominates over radiation.
We show that for some choice of T_r not far from the RHN mass M,
M/100
5 MeV (M/TeV) (0.05 eV/m) must be verified,
with m the effective neutrino mass scale.
