Abstract. Through
leptogenesis, baryogenesis
could have the same origin as
neutrino masses. We review the
various ways of implementing
the leptogenesis
mechanism. Emphasis is put on the
conditions which, in order that
this mechanism works,
need to be fulfilled by the
neutrino masses as well as by the
heavy state masses.
Keywords. Baryogenesis; neutrino masses.
