  3. The D0 Experiment Fermilab • Group • Faculty: • J. Butler, • U. Heintz, • M. Narain • Students: • S. Fatakia, • K. Black, • L. Felligioni • S. Rappocio, • Y. Kratsnisky

  4. The D0 experiment muon detector • Proton-antiproton collisions • Ecom = 2 TeV • highest Ecom ! • Top quark (discovery) • W and Z bosons (precision measurements) • Physics beyond SM • Search for • Higgs • Supersymmetry • Technicolor • others calorimeter tracker 5000 tons 400 physicists Run I: 1992-1996 100 pb-1 80 publications 100 Ph.D.s

  5. silicon detector 0.5 mm top Higgs SUSY Technicolor 800,000 channels 10 m hit resolution 1 m b 1 B(b  + X)  20%  detect muons 2 life time  1.5 ps  c  0.5 mm precise tracking silicon microstrip detectors

  6. What are we doing? • Trigger Electronics • interaction rate: 2 MHz • max readout rate: 50 Hz • recognize interesting events online • muon trigger • silicon trigger • state-of-the-art, high-speed digital electronics

  7. The Super-K/K2K Experiments • Group: • Faculty: • E. Kearns, L. Sulak, J. Stone • Postdoctoral fellows: • A. Habig, K. Scholberg, C. Walter • Students: • S. Desai, M. Earl, S. Rich, C. Orth

  8. Super-Kamiokande down up 

  9. The g-2 Experiment • Group

  10. The g-2 Experiment • Due to its magnetic moment • a muon precesses in a magnetic field • a precise measurement of gm is sensitive to • internal structure of muon • new heavy particles that interact with the muon

  11. The g-2 Experiment Brookhaven

  12. The Large Hadron Collider • Proton-proton collisions at 14 TeV • probe SM in new energy regime CMS Higgs ATLAS

  13. The ATLAS Detector

  14. ATLAS Muon Chambers

  15. ATLAS Electronics Mezzanine board Electronics stack ASD Chips Endcap chamber Hedgehog board All being built at BU and Harvard.
