Two-Higgs-Doublet Models with CP violation
Ilya F. Ginzburg, Maria Krawczyk, Per Osland
We consider the Two-Higgs-Doublet Model and determine the range of parameters for which CP violation and Flavor Changing Neutral Current effects are naturally small. It corresponds…
Model-independent constraints on contact interactions from LEP2 data analysis
A. A. Babich, G. Della Ricca, J. Holt +3
We derive model-independent constraints on four-fermion contact interaction-type dynamics from the published preliminary LEP2 experimental data on e^+e^- annihilation into μ^+μ^- a…
Three-Neutrino MSW Effect and the Lehmann Mass Matrix
Per Osland
Recent work on analytical solutions to the MSW equations for three neutrino flavours is reviewed, with emphasis on the exponential density. Application to a particular mass matrix,…
Neutrino masses from universal Fermion mixing
R. Gastmans, Per Osland, Tai Tsun Wu
If three right-handed neutrinos are added to the Standard Model, then, for the three known generations, there are six quarks and six leptons. It is then natural to assume that the…
Graviton-induced Bremsstrahlung
Erik Dvergsnes, Per Osland, Nurcan Ozturk
We discuss photon Bremsstrahlung induced by virtual graviton exchange in proton-proton interactions at hadronic colliders, resulting from the exchange of Kaluza-Klein excitations o…
