TL;DR: In this article, general expressions for the oblique parameters S, T, U, V, W, and X in the SU(2)×U(1) electroweak model with an arbitrary number of scalar SU( 2) doublets, with hypercharge ± 1/2, and an arbitrary scalar singlets.

TL;DR: In this article, the authors reviewed all existing evidence and indications in favour of neutrino oscillations that have been obtained in the atmospheric, solar and LSND experiments and investigated possibilities to test the different neutrinos mass and mixing schemes obtained in this way.

TL;DR: In this paper, a non-abelian symmetry group was proposed to enforce maximal atmospheric neutrino mixing, while θ 13 = 0 and the solar mixing angle θ 12 remains undetermined.

TL;DR: In this paper, a general expression for Δρ for the oblique parameter T in the SU(2) × U(1) electroweak model with an arbitrary number of scalar SU( 2) doublets, with hypercharge ± 1/2, was derived.

TL;DR: In this article, a neutrino mass matrix M ν originally found by Babu, Ma, and Valle (BMV) was characterized by a simple algebraic relation, and it was shown that atmospheric mixing is exactly maximal while at the same time an arbitrary mixing angle θ13 of the lepton mixing matrix U is allowed and CP violation in mixing is maximal.
