The Neutralino Sector in the U(1)-Extended Supersymmetric Standard Model

S. Y. Choi, H. E. Haber, J. Kalinowski +1

Motivated by grand unified theories and string theories we analyze the general structure of the neutralino sector in the USSM, an extension of the Minimal Supersymmetric Standard M…

Baryogenesis, Dark Matter and the Pentagon

T. Banks, S. Echols, J. L. Jones

We present a new mechanism for baryogenesis, which links the baryon asymmetry of the universe to the dark matter density. The mechanism arises naturally in the Pentagon model of Te…

Remodeling the Pentagon After the Events of 2/23/06

T. Banks

The meta-stable SUSY breaking mechanism of Intriligator Seiberg and Shih can be used to simplify the Pentagon model of TeV scale physics. The simplified model has only a single sca…

Little Higgs Dark Matter

Andreas Birkedal, Andrew Noble, Maxim Perelstein +1

The introduction of T parity dramatically improves the consistency of Little Higgs models with precision electroweak data, and renders the lightest T-odd particle (LTP) stable. In…

Basis-independent methods for the two-Higgs-doublet model II. The significance of tan(beta)

Howard E. Haber, Deva O'Neil

In the most general two-Higgs-doublet model (2HDM), there is no distinction between the two complex hypercharge-one SU(2) doublet scalar fields, Phi_a (a=1,2). Thus, any two orthon…

Quantum corrections to the MSSM h^0 b b-bar vertex: Decoupling limit

Howard E. Haber, Heather E. Logan, Siannah Penaranda +1

We consider the leading one-loop Yukawa-coupling corrections to the h^0 b b-bar coupling at O(m_t^2)in the MSSM in the decoupling limit. The decoupling behavior of the corrections…
