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…

Constraining the Two-Higgs-Doublet-Model parameter space
Abdul Wahab El Kaffas, Odd Magne Ogreid, Per Osland
We confront the Two-Higgs-Doublet Model with a variety of experimental constraints as well as theoretical consistency conditions. The most constraining data are the \bar B\to X_sγd…
