Spin identification of the Randall-Sundrum resonance in lepton-pair production at the LHC
P. Osland, A. A. Pankov, N. Paver +1
The determination of the spin of the quantum states exchanged in the various non-standard interactions is a relevant aspect in the identification of the corresponding scenarios. We…
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…
Trilinear Higgs couplings in the two Higgs doublet model with CP violation
Per Osland, P. N. Pandita, Levent Selbuz
We carry out a detailed analysis of the general two Higgs doublet model with CP violation. We describe two different parametrizations of this model, and then study the Higgs boson…
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…
Radiative gravitino decays from R-parity violation
S. Lola, P. Osland, A. R. Raklev
We study radiative gravitino decay within the framework of R-violating supersymmetry. For trilinear R-violating couplings that involve the third generation of fermions, or for ligh…
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…
