Basis-independent methods for the two-Higgs-doublet model III: The CP-conserving limit, custodial symmetry, and the oblique parameters S, T, U

Howard E. Haber, Deva O'Neil

In the Standard Model, custodial symmetry is violated by the hypercharge U(1) gauge interactions and the Yukawa couplings, while being preserved by the Higgs scalar potential. In t…

Present status and future prospects for a Higgs boson discovery at the Tevatron and LHC

Howard E. Haber

Discovering the Higgs boson is one of the primary goals of both the Tevatron and the Large Hadron Collider (LHC). The present status of the Higgs search is reviewed and future pros…

Geometric picture of generalized-CP and Higgs-family transformations in the two-Higgs-doublet model

P. M. Ferreira, Howard E. Haber, M. Maniatis +2

In the two-Higgs-doublet model (THDM), generalized-CP transformations (phi_i--> X_{ij} phi_j^* where X is unitary) and unitary Higgs-family transformations (phi_i--> U_{ij} phi_j)…

Supersymmetric Monojets at the Large Hadron Collider

Benjamin C. Allanach, Sebastian Grab, Howard E. Haber

Supersymmetric monojets may be produced at the Large Hadron Collider by the process qg -> squark neutralino_1 -> q neutralino_1 neutralino_1, leading to a jet recoiling against mis…

Singlet Scalar Dark Matter: monochromatic gamma rays and metastable vacua

Stefano Profumo, Lorenzo Ubaldi, Carroll Wainwright

We calculate the pair-annihilation cross section of real scalar singlet dark matter into two mono-energetic photons. We derive constraints on the theory parameter space from the Fe…

Stau as the Lightest Supersymmetric Particle in R-Parity Violating SUSY Models: Discovery Potential with Early LHC Data

K. Desch, H. K. Dreiner, S. Fleischmann +2

We investigate the discovery potential of the LHC experiments for R-parity violating supersymmetric models with a stau as the lightest supersymmetric particle (LSP) in the framewor…

A Comprehensive Analysis of Electric Dipole Moment Constraints on CP-violating Phases in the MSSM

Yingchuan Li, Stefano Profumo, Michael Ramsey-Musolf

We analyze the constraints placed on individual, flavor diagonal CP-violating phases in the minimal supersymmetric extension of the Standard Model (MSSM) by current experimental bo…

Bounds on R-parity Violating Couplings at the Grand Unification Scale from Neutrino Masses

H. K. Dreiner, S. Grab, M. Hanussek

We consider the embedding of the supersymmetric Standard Model with broken R-parity in the minimal supergravity (mSUGRA) model. We restrict ourselves to the case of broken lepton n…

Basis invariant conditions for supersymmetry in the two-Higgs-doublet model

P. M. Ferreira, Howard E. Haber, Joao P. Silva

The minimal supersymmetric standard model involves a rather restrictive Higgs potential with two Higgs fields. Recently, the full set of classes of symmetries allowed in the most g…

SUSY parameter determination at the LHC using cross sections and kinematic edges

Herbi K. Dreiner, Michael Krämer, Jonas M. Lindert +1

We study the determination of supersymmetric parameters at the LHC from a global fit including cross sections and edges of kinematic distributions. For illustration, we focus on a…
