Spin and model identification of Z' bosons at the LHC

P. Osland, A. A. Pankov, N. Paver +1

Heavy resonances appearing in the clean Drell-Yan channel may be the first new physics to be observed at the proton-proton CERN LHC. If a new resonance is discovered at the LHC as…

Natural Multi-Higgs Model with Dark Matter and CP Violation

B. Grzadkowski, O. M. Ogreid, P. Osland

We explore an extension of the Inert Doublet Model which allows also for CP violation in the Higgs sector. This necessitates two non-inert doublets. The lightest neutral scalar of…

Pion Mass Shift and the Kinetic Freeze Out Process

Sven Zschocke, Laszlo P. Csernai

The kinetic Freeze Out process of a pion gas through a finite layer with time-like normal is considered. The pion gas is described by a Boltzmann gas with elastic collisions among…

Gravitino Dark Matter and the Flavour Structure of R-violating Operators

N. -E. Bomark, S. Lola, P. Osland +1

We study gravitino dark matter and slow gravitino decays within the framework of R-violating supersymmetry, with particular emphasis on the flavour dependence of the branching rati…

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…
