Gauge-Higgs Unification and Radiative Electroweak Symmetry Breaking in Warped Extra Dimensions
of large corrections to the T parameter and the coupling of the Z to the bottom quark. We demonstrate that electroweak symmetry breaking may be realized, with proper generation of the top and bottom
Potential discovery of staus through heavy Higgs boson decays at the LHC
A bstractIn this work we present a new search strategy for the discovery of staus at the LHC in the context of the minimal supersymmetric standard model. The search profits from the large s-channel
The scale-invariant NMSSM and the 126 GeV Higgs boson
A bstractThe recent LHC discovery of a Higgs-like resonance at 126 GeV suggests that the minimal supersymmetric standard model must be modified in order to preserve naturalness. A simple extension is
Gauge-Higgs Unification, Neutrino Masses and Dark Matter in Warped Extra Dimensions
Gauge-Higgs unification in warped extra dimensions provides an attractive solution to the hierarchy problem. The extension of the standard model gauge symmetry to SO(5)xU(1){sub X} allows the
Collider phenomenology of Gauge-Higgs unification scenarios in warped extra dimensions
We compute the couplings of the zero modes and first excited states of gluons, W's, Z gauge bosons, as well as the Higgs, to the zero modes and first excited states of the third generation quarks, in
The price of being SM-like in SUSY
A bstractWe compute the tuning in supersymmetric models associated with the constraints from collider measurements of the Higgs couplings to fermions and gauge bosons. In supersymmetric models, a CP
Leptophilic dark matter with Z ' interactions
We consider a scenario where dark matter (DM) interacts exclusively with Standard Model (SM) leptons at tree level. Due to the absence of tree-level couplings to quarks, the constraints on
SUSY implications from WIMP annihilation into scalars at the Galactic Center
An excess in $\gamma$-rays emanating from the galactic centre has recently been observed in the Fermi-LAT data. We investigate the new exciting possibility of fitting the signal spectrum by dark
Co-annihilating Dark Matter: Effective Operator Analysis and Collider Phenomenology
We study dark matter (DM) models in which there are two dark sector particles, $\chi_1$ and $\chi_2$, of near mass. In such models, co-annihilation of $\chi_1$ and $\chi_2$ may be the dominant
