Although many methods have been proposed to understand the dynamics of chiral gauge theories, each has its own set of issues. AMSB is a promising new technique that allows one to use the solvability of SUSY chiral theories and translate that in a standard way into non-susy theories. I will discuss how this new method works and apply it to … Read More

Abstract: I describe a reanalysis of data sets that have previously been found to harbor evidence for an unidentified X-ray line at 3.5 keV in order to quantify the robustness of earlier results that found significantevidence for a new X-ray line at this energy. The 3.5 keV line is intriguing in part because of possible connections to dark matter. We analyze … Read More
