High energy neutrinos from neutralino annihilations in the Sun
Vernon Barger, Wai-Yee Keung, Gabe Shaughnessy +1
Neutralino annihilations in the Sun to weak boson and top quark pairs lead to high-energy neutrinos that can be detected by the IceCube and KM3 experiments in the search for neutra…
LHC Phenomenology of an Extended Standard Model with a Real Scalar Singlet
Vernon Barger, Paul Langacker, Mathew McCaskey +2
Gauge singlet extensions of the Standard Model (SM) scalar sector may help remedy its theoretical and phenomenological shortcomings while solving outstanding problems in cosmology.…
Singlet Higgs Phenomenology and the Electroweak Phase Transition
Stefano Profumo, Michael J. Ramsey-Musolf, Gabe Shaughnessy
We study the phenomenology of gauge singlet extensions of the Standard Model scalar sector and their implications for the electroweak phase transition. We determine the conditions…
Precision gluino mass at the LHC in SUSY models with decoupled scalars
Howard Baer, Vernon Barger, Gabe Shaughnessy +2
One way to ameliorate the SUSY flavor and CP problems is to postulate that scalar masses lie in the TeV or beyond regime. For example, the focus point (FP) region of the minimal su…
Recoil Detection of the Lightest Neutralino in MSSM Singlet Extensions
Vernon Barger, Paul Langacker, Ian Lewis +3
We investigate the correlated predictions of singlet extended MSSM models for direct detection of the lightest neutralino with its cosmological relic density. To illustrate the gen…
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…
