Dark matter in natural supersymmetric extensions of the Standard Model
Francesc Ferrer, Christopher Spitzer
We explore the dark matter sector in extensions of the Minimal Supersymmetric Standard Model (MSSM) that can provide a good fit to the PAMELA cosmic ray positron excess, while at t…
Protecting unparticles from the MSSM Higgs sector
Ann E. Nelson, Maurizio Piai, Christopher Spitzer
We construct a model of an unparticle sector consisting of a supersymmetric SU(N) gauge theory with the number of flavors in the Seiberg conformal window. We couple this sector to…
Slightly Non-Minimal Dark Matter in PAMELA and ATIC
Ann E. Nelson, Christopher Spitzer
We present a simple model in which dark matter couples to the standard model through a light scalar intermediary that is itself unstable. We find this model has several notable fea…
Stability in MaVaN Models
Christopher Spitzer
Mass-varying neutrino (MaVaN) models propose a source of dark energy in a new scalar field called the acceleron. Recent work has shown that nonrelativistic neutrino fields in these…
