一个新的轻子混合A4模型

A new A4 model for lepton mixing

P. M. Ferreira, L. Lavoura, P. O. Ludl

摘要:

我们提出了一个新的模型的轻子部门,使用一个家庭的对称性A4的轻子混合下的三种口味的任何排列是不变的预测。我们发现,这些预测与实验数据基本一致,导致较大的sin ^2(θ 12)>~ 0.34,|cos(delta)|>~ 0.7,且|0.5 - sin^2(θ 23)|>~ 0.08; cos(delta)和0.5 -sin ^2(θ 23)的符号预计相同。

英文摘要:

We present a new model of the lepton sector that uses a family symmetry A4 to make predictions for lepton mixing which are invariant under any permutation of the three flavours. We show that those predictions broadly agree with the experimental data, leading to a largish sin^2(theta12) >~ 0.34, to |cos(delta)| >~ 0.7, and to | 0.5 - sin^2(theta23) | >~ 0.08; cos(delta) and 0.5 - sin^2(theta23) are predicted to have identical signs.
