Theory and phenomenology of two-Higgs-doublet models
Abstract We discuss theoretical and phenomenological aspects of two-Higgs-doublet extensions of the Standard Model. In general, these extensions have scalar mediated flavour changing neutral currentsExpand
Working Group Report: Higgs Boson
This report summarizes the work of the Energy Frontier Higgs Boson working group of the 2013 Community Summer Study (Snowmass). We identify the key elements of a precision Higgs physics program andExpand
Electroweak Higgs Potentials and Vacuum Stability
Abstract In electroweak models, radiative corrections to the scalar potential can have significant consequences. In the standard model, they can destabilize the standard model vacuum; the requirementExpand
Lifetime of the electroweak vacuum and sensitivity to Planck scale physics
If the Standard Model (SM) is valid up to extremely high energy scales, then the Higgs potential becomes unstable at approximately 1 0 11 GeV . However, calculations of the lifetime of the SM vacuumExpand
Bounds on ΔB = 1 couplings in the supersymmetric standard model
The most general supersymmetric model contains baryon number violating terms of the form {lambda}{sub ijk} {bar D}{sub i}{bar D}{sub j}{bar U}{sub k} in the superpotential. The authors reconsider theExpand
Holographic electroweak symmetry breaking from D-branes
We observe several interesting phenomena in a technicolor-like model of electroweak symmetry breaking based on the D4-D8-D8 system of Sakai and Sugimoto. The benefit of holographic models based onExpand
Vacuum Stability Bounds in the Two-Higgs Doublet Model
Abstract In the standard model, the requirements of vacuum stability and the validity of perturbation theory up to the unification scale force the mass of the Higgs boson to be approximately betweenExpand
Quarks and Leptons Beyond the Third Generation
Abstract The possibility of additional quarks and leptons beyond the three generations already established is discussed. The make-up of this Report is (1)  Introduction : the motivations forExpand
Photon mass at low temperature?
The theoretical observation that gauge symmetries are generally restored at sufficiently high temperature has led us to consider here the conjecture that gauge symmetries are broken at sufficientlyExpand
Charge/color breaking minima and A-parameter bounds in supersymmetric models☆
In supersymmetric models, the requirement that the global potential minimum not violate color and/or electric charge invariance implies restrictions on the parameters of the model. We reassess andExpand
