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...
