Photoproduction of Heavy Flavours

Overview of the E687/FOCUS spectrometer:
The FERMILAB E687 Collaboration studies production and decay properties of heavy flavours produced in photon-hadron interactions. The experiment recorded approximately 500 million hadronic triggers in the 1990-91 fixed target run at Fermilab from which over 80 thousand charm decays were fully reconstructed. Physics publications include the precision lifetime measurements of the charm hadrons, D meson semileptonic form factors, detailed Dalitz plot analyses, charm meson and baryon decay modes and spectroscopy, searchs for rare and forbidden phenomena, and tests of QCD production mechanisms. The follow-on experiment FOCUS COLLABORATION (FERMILAB E831) successfully recorded huge amount of data during the 1996-1997 fixed target run, and is currently analyzing the data set fervently.
