Z' Discovery Limits For Supersymmetric E_6 Models
Junhai Kang, Paul Langacker
We study how the exotic particles and supersymmetric partners would affect the discovery limit at the Tevatron and LHC for neutral gauge bosons in generic E_6 models. We examine th…
Muon Anomalous Magnetic Moment in a Supersymmetric U(1)' Model
Vernon Barger, Chung Kao, Paul Langacker +1
We study the muon anomalous magnetic moment a_μ= (g_μ- 2)/2 in a supersymmetric U(1)' model. The neutralino sector has extra components from the superpartners of the U(1)' gauge bo…
Neutrino Physics (theory)
Paul Langacker
Nonzero neutrino masses are the first definitive need to extend the standard model. After reviewing the basic framework, I describe the status of some of the major issues, includin…
Neutrino Masses in Supersymmetric SU(3)_C x SU(2)_L x U(1)_Y x U(1)' Models
Junhai Kang, Paul Langacker, Tianjun Li
We consider various possibilities for generating neutrino masses in supersymmetric models with an additional U(1)' gauge symmetry. One class of models involves two extra U(1)' x U(…
Neutralino Relic Density in a Supersymmetric U(1)' Model
Vernon Barger, Chung Kao, Paul Langacker +1
We study properties of the lightest neutralino (χ) and calculate its cosmological relic density in a supersymmetric U(1)' model with a secluded U(1)' breaking sector (the S-model).…
Electroweak Model and Constraints on New Physics
Jens Erler, Paul Langacker
Section 10 of the 2004 edition of the Review of Particle Physics.
