 | Gamma Rays at 130 GeV and How They Might Come from Dark Matter Speaker(s): Andrew Frey
Abstract: Gamma Rays at 130 GeV and How They Might Come from Dark
Matter"
I'll discuss the exciting (but somewhat controversial)
new discovery of a sharp gamma ray feature at 130 GeV from near the galactic
center and review some other evidence that might link it to annihilation of
dark matter. I ... read more

An Inverted Mass Hierarchy for Excited Dark Matter Speaker(s): Andrew Frey
Abstract: Varied experimental results have recently sparked theoretical interest in the dark matter sector. I will review some of these results and the basic ideas in particle physics that might explain them, as well as some requirements for those models to work. Then I'll discuss a new model dark matter sect... read more

Backreaction in Closed String Tachyon Condensation Speaker(s): Andrew Frey
Abstract: Working in the weak tachyon region of a condensing tachyon background, we find the modified equations of motion for massless strings with conformal perturbation theory. We then estimate the backreaction on the background dilaton. In large (supercritical) dimensions, we find that the backreaction can... read more
