Fermilab May 2004 The Future of QCD: K. Goulianos25 Hard Diffraction Conclusions Diffraction appears to be a low-x exchange subject to color constraints

Fermilab May 2004 The Future of QCD: K. Goulianos32 Hard Double Diffraction Question Run I Results

Fermilab May 2004 The Future of QCD: K. Goulianos33 Exclusive Dijets in DPE Interest in diffractive Higgs production Calibrate on exclusive dijets Upper limit for excl DPE-jj consistent with theory Dijet mass fraction no peak!

Fermilab May 2004 The Future of QCD: K. Goulianos34 Search for Exclusive  Events are triggered on dimuons Select muons with P T >1.5 GeV, |  |< 0.6 Reject cosmic rays using time of flight information Select events in J/  mass window 10  c candidates No positive identification of  c events Cross section upper limit comparable to KMR prediction

Fermilab May 2004 The Future of QCD: K. Goulianos35 Merits/Problems/Needs Merits of CDF Run II diffractive program  Measuring  with calorimeters  full acceptance  overlap rejection  BSC gap triggers  can take data at high luminosities But:  BSC gap rejects some diffractive events from MP spillover  Useful rates too low for many processes, e. g. exclusive b-bbar Need:  Low luminosity runs for calibrations:   -roman pot vs  -calorimeter  BSC gap trigger vs roman pot trigger Also need:  $$$ to instrument MPs from current 84 to all 256 channels for EM/hadron discrimination and better jet definition

Fermilab May 2004 The Future of QCD: K. Goulianos36 CONCLUSION Run II  CDF has a comprehensive Run II diffractive program  Modest upgrades & special runs are desirable  Full MiniPlug instrumentation  Low luminosity (~10 30 ) runs for calibrations  Data run at 630 GeV Beyond Run II  Can think of improvements, but of no compelling diffractive physics that cannot be done in Run II
