摘要
The basic principle of naturalness has driven the majority of the LHC program, but so far all searches for new physics beyond the SM have come up empty. On the other hand, existing measurements of SM processes contain interesting anomalies, which allow for the possibility of new physics with mass scales very close to the electroweak scale. In this paper we show that SUSY could have stops with masses O(200) GeV based on an anomaly in the W+W- cross section, measured by both ATLAS and CMS at 7 and 8 TeV. In particular we show that there are several different classes of stop-driven scenarios that not only evade all direct searches, but also improve the agreement with the data in the SM measurement of the W+W- cross section.
