Natural SUSY in Plain Sight
David Curtin, Patrick Meade, Pin-Ju Tien

TL;DR
This paper proposes that natural supersymmetry could manifest with light stops around 200 GeV, explaining anomalies in WW cross section measurements and evading current direct search constraints.
Contribution
It introduces scenarios where light stops near 200 GeV explain WW anomalies and evade existing LHC searches, offering a new perspective on natural SUSY.
Findings
Light stops (~200 GeV) can explain WW cross section anomalies.
Certain SUSY scenarios improve agreement with SM measurements.
These scenarios evade current direct search constraints.
Abstract
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 WW 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 improve the agreement with the data in the SM measurement of the WW cross section.
