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…
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).…
Solution to the B -> pi K Puzzle in a Flavor-Changing Z' Model
Vernon Barger, Cheng-Wei Chiang, Paul Langacker +1
Recent experiments suggest that certain B -> pi K branching ratios are inconsistent with the standard model expectations. We show that a flavor-changing Z' provides a solution to t…
Neutrino physics from new SNO and KamLAND data and future prospects
A. B. Balantekin, V. Barger, D. Marfatia +2
We analyze the cumulative data from the latest SNO, KamLAND and other solar neutrino experiments in the standard scenario of three oscillating active neutrinos. We determine the so…
Big Bang Nucleosynthesis Constraints on Z' Properties
Vernon Barger, Paul Langacker, Hye-Sung Lee
In models involving new TeV-scale Z' gauge bosons, the new U(1)' symmetry often prevents the generation of Majorana masses needed for a conventional neutrino seesaw, leading to thr…
