Current BNL HEP ActivitiesCurrent BNL HEP Activities
Approaching the Energy Frontier - Higgs, SUSY, ??? D0 Upgrade - Preshower Det. & Software; D0 physics Run 2 startup Host Lab for US ATLAS Construction & Computing Projects - LHC dets. & physics Partner Lab for LHC Accelerator Project - SC magnets & cable testing SNO and MINOS neutrino experiments (collaborators)
Probing beyond the Frontier! - rare processes/precision meas. Muon (g-2) & rare K decay experiments at AGS - propagator physics!
Understanding the patterns - theory Strong HEP Theory Group in current topical areas Riken BNL Research Center with 0.6 Tflops QCDSP Supercomputer
Inventing the tools - future machines & technologies Accelerator Physics and Superconducting Magnet R&D:
- ATF, muon storage ring/collider, HTSC magnet concepts Key investment!

D0 search for Higgs/SUSY in the moderate mass regime US Host Lab for ATLAS LHC physics & Tier-1 Computing Center
Probing beyond the Frontier! - ‘RSVP’ MECO ( -> e direct conversion) - new physics up to 3000 TeV mass scale! KOPIO & CKM (K0
L -> 0 bar) - golden decay for CP-violation parameter
Muon electric dipole moment (EDM) search/measurement?
Understanding the patterns - theory Strong HEP Theory Group in key topical areas, including lattice gauge! Riken BNL Research Center with 10 Tflops QCDOC next generation SC Lattice Gauge Center with 20 Tflops QCDOC Supercomputer
