SUMMARY:New frontiers in LHC discovery strategies - Jesse Liu (University 
 of Oxford)

DESCRIPTION:The LHC could already be a dark matter factory and we would ha
 ve no idea. Key targets in supersymmetry illustrate this pressing problem\
 , such as 100 GeV Higgsinos\, whose cross-sections would mean over a milli
 on signal events produced to date. But formidable backgrounds obscure its 
 challenging soft lepton signatures in ATLAS. One interesting proposal uses
  the LHC as a photon collider sourced by electric fields surrounding the p
 rotons. Tagging intact protons could allow full missing momentum reconstru
 ction for the first time at hadron colliders\, opening a new frontier for 
 discovering dark matter.
