Dark matter and pulsar signals for Fermi LAT, PAMELA, ATIC, HESS and WMAP data
V. Barger, Y. Gao, W. -Y. Keung +2
We analyze new diffuse gamma-ray data from the Fermi Gamma-ray Space Telescope, which do not confirm an excess in the EGRET data at galactic mid-latitudes, in combination with meas…
Dark Matter: The Leptonic Connection
Qing-Hong Cao, Ernest Ma, Gabe Shaughnessy
Recent observatons of high-energy positrons and electrons by the PAMELA and ATIC experiments may be an indication of the annihilation of dark matter into leptons and not quarks. Th…
Complex Singlet Extension of the Standard Model
Vernon Barger, Paul Langacker, Mathew McCaskey +2
We analyze a simple extension of the Standard Model (SM) obtained by adding a complex singlet to the scalar sector (cxSM). We show that the cxSM can contain one or two viable cold…
SUSY backgrounds to Standard Model calibration processes at the LHC
Howard Baer, Vernon Barger, Gabe Shaughnessy
One of the first orders of business for LHC experiments after beam turn-on will be to calibrate the detectors using well understood Standard Model (SM) processes such as W and Z pr…
TeV physics and the Planck scale
Vernon Barger, Paul Langacker, Gabe Shaughnessy
Supersymmetry is one of the best motivated possibilities for new physics at the TeV scale. However, both concrete string constructions and phenomenological considerations suggest t…
Neutralino Signatures of the Singlet Extended MSSM
Vernon Barger, Paul Langacker, Gabe Shaughnessy
Extending the Higgs sector of the MSSM by the addition of a gauge singlet scalar field can remedy the mu problem. We explore the implications of extended models for both the spectr…
