New Probes for Physics BSM at the LHC P-23,
P-25, T-8 and T-16

• LHC is the first facility where high energy jets
  are copiously produced, e.g
• pp? Z0 jet
• Use CMS (Compact Muon Solenoid) experiments
  excellent muon identification and calorimetry
  for detection
• Examine topology of these events in the vacuum
  and in nuclear collisions
• Discovery potential for BSM Physics -
  Supersymmetry, Higgs, etc.
• Radiography of the Quark-Gluon Plasma - Matter
  under extreme conditions
• Existing LDRD-ER grant predicts excellent rates
  for jet tagging at CMS experiment

New Probes for Physics BSM at the LHC

• Potential LANL contributions to CMS / LHC
• program
• Large scale event simulation
• Offline event reconstruction (large computing
  resources)
• Theory for interpretation of data -
  supersymmetry, energy loss, etc.
• LHC schedule -
• First pp collisions in 2008
• Heavy Ions to follow, probably 2010
• LHC is future of HEP and High Energy Nuclear
  Physics programs - Timely opportunity to
  establish a new program at LHC. Seed money to
  ensure long-term DOE funding for NP program.
  Possible HEP support
