We are currently working on the extension to this theory, suggested by Itay Yavin and others, which can be found here.
Experimental Signature
The signature is many leptons (electrons or muons, although the SLAC group has been focusing on the muonic final state) in the same cone, resembling a jet. For ATLAS, the leptons usually fall in the same ROI (Region of Interest), requiring additional trigger chains to be sensitive to these events.
