FOCUS, aka E831, is a heavy-flavor photoproduction experiment located in the Wide Band Area of Fermilab. It is an upgraded version of its predecessor, E687. The experiment accumulated data during the 1996-1997 fixed target run and has fully reconstructed more than one million charm particles using the `golden mode' decays, D0→ K π+, D0→ K π+ π π+, and D+→ K π+ π+.


Analysis efforts include:
  • High precision studies of charm semileptonic decays
  • Studies of hadronic charm decays (branching ratios and Daltiz analyses)
  • Lifetime measurements of all charm particles
  • Searches for mixing, CP/CPT violation, rare and forbidden decays
  • Spectroscopy of excited charm mesons and baryons
  • Searches for and upper limits on:
    • -->Pentaquarks
    • Double charm baryons
    • DsJ(2632)
  • Charm production asymmetry measurements
  • Light quark diffractive studies
  • QCD studies using charm pair events
