Charginos Hiding In Plain Sight

Recently, ATLAS and CMS measured both overall and differential W+W- cross sections that differ from next to leading order standard model predictions. While these measurements are not yet statistically significant enough to rule out the standard model, we demonstrate that the data from both experiments can be better fit with the inclusion of electroweak gauginos with masses of O(100) GeV. We show that these gauginos are consistent with other searches or measurements and can have ramifications for Higgs phenomenology.

Note:

7 pages, 3 figures v2:significant updates incorporating summer experimental results, conclusions strengthened
