Economical extensions of the Standard Model (SM), in which famous Davidson–Ibarra bound on the CP asymmetry relevant for leptogenesis may be significantly relaxed by the loop effects, comparing to predictions of the SM extended only by heavy right-handed neutrinos with hierarchical masses, are discussed. This leads to decreasing of the lower bound on the heavy neutrino masses and increasing of the upper bound on the light neutrino masses, which is testable. In addition, the considered theory may help to solve the dark matter problem.
