abstract = {During the process of thermal leptogenesis temperature
decreases by about one order of magnitude while the baryon
asymmetry is generated. We present an analytical description
of this process so that the dependence on the neutrino mass
parameters becomes transparent. In the case of maximal CP
asymmetry all decay and scattering rates in the plasma are
determined by the mass $M_1$ of the decaying heavy Majorana
neutrino, the effective light neutrino mass $tilde{m}_1$ and
the absolute mass scale bar{m} of the light neutrinos. In
the mass range suggested by neutrino oscillations, $m_{sol}$
$\simeq$ $8*10^{-3}$ eV $\lesssim$ $\tilde{m}_1$ $\lesssim$
$m_{atm}$ $\simeq$ $5*10^{-2}$ eV, leptogenesis is dominated
just by decays and inverse decays. The effect of all other
scattering processes lies within the theoretical uncertainty
of present calculations. The final baryon asymmetry is
dominantly produced at a temperature $T_B$ which can be
about one order of magnitude below the heavy neutrino mass
$M_1.$ We also derive an analytical expression for the upper
bound on the light neutrino masses implied by successful
leptogenesis.},
