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
