| 英文摘要 | In this talk, we first give a brief review of the so-called minimal seesaw models and then concentrate on the minimal type-I seesaw model with two almost degenerate right-handed Majorana neutrinos of O (1 TeV). A specific texture of the neutrino Yukawa coupling matrixis proposed to achieve the nearly tri-bimaximal neutrino mixing pattern. This ansatz predicts (1) theta(23) = pi/4, \delta\ = pi/2 and sin(2) theta(12) = (1-2 tan(2) theta(13))/3 in the m(1) = 0 case; and (2) theta(23) = pi/4 and theta(13) = delta = 0 in the m(3) = 0 case. In both cases, the cosmological baryon number asymmetry can be explained via the resonant leptogenesis mechanism. Finally, we demonstrate the significance of flavor-dependent effects in our leptogenesis scenario. |
