The Problem of Large Leptonic Mixing

Unlike in the quark sector where simple $S_3$ permutation symmetries can generate the general features of quark masses and mixings, we find it impossible, without considering the see-saw mechanism or a more elaborate extension of the SM, to obtain large leptonic mixing angles with any general symmet...

description Unlike in the quark sector where simple $S_3$ permutation symmetries can generate the general features of quark masses and mixings, we find it impossible, without considering the see-saw mechanism or a more elaborate extension of the SM, to obtain large leptonic mixing angles with any general symmetry or transformation of only known particles. If such symmetries exist, they must be realized in more extended scenarios.
