The oblique parameters in multi-Higgs-doublet models
W. Grimus, L. Lavoura, O. M. Ogreid +1
We present general expressions for the oblique parameters S, T, U, V, W, and X in the SU(2)xU(1) electroweak model with an arbitrary number of scalar SU(2) doublets, with hyperchar…
A precision constraint on multi-Higgs-doublet models
W. Grimus, L. Lavoura, O. M. Ogreid +1
We derive a general expression for Delta rho (or, equivalently, for the oblique parameter T) in the SU(2) x U(1) electroweak model with an arbitrary number of scalar SU(2) doublets…
A_4 model for the quark mass matrices
L. Lavoura, H. Kuhbock
We propose a model for the quark masses and mixings based on an A_4 family symmetry. Three scalar SU(2) doublets form a triplet of A_4. The three left-handed-quark SU(2) doublets a…
Models of maximal atmospheric neutrino mixing
W. Grimus, L. Lavoura
We discuss two types of neutrino mass matrices which both give , i.e., a maximal atmospheric mixing angle. We review three models, based on the seesaw mechanism…
