论文摘要
我们提出了一个想法,即中微子振荡中观察到的CP违规源于右手中微子通过Seesaw机制混合的相位。我们在$ a_4 $对称性的模型中添加了小的破碎项$ m_ {ij} n_ {r_i} n_ {r_j} $,以生成非二角右手中微子混合,这将通过seeSAW机制与非零反应器角度和违反CP违反CP的tbm机制进行较小的校正。我们通过研究由于右手中微子的衰减而估计违反CP违反阶段的。
We propose an idea that the observed CP violation in neutrino oscillation is originated from the phase in right-handed neutrino mixing by seesaw mechanism. We add small breaking terms $M_{ij}N_{R_i}N_{R_j} $ in model based on $A_4$ symmetry to generate non-diagonal right-handed neutrino mixing, which will give a small correction to TBM mixing via seesaw mechanism with nonzero reactor angle and CP violating phase. We estimate the CP violating phase by investigating the process of leptogenesis due to the decay of right-handed neutrino.
