Future of QCD Physics at the Tevatron
Andrew Brandt, University of Texas at Arlington

• May 20-22 Workshop at Fermilab to discuss
  currentfuture QCD
• Largely motivated by Mike Albrow my interest in
• a future new QCD experiment GTeV
• Connection to DØ?

DØ Collab Meeting Fermilab Feb. 27, 2004

GTeV Gluon Physics at the Tevatron

• A future experiment at the Fermilab Tevatron
• 2009 CDF DØ complete data taking
• BTeV to run 2009-2014(?)
• Primary Goal of GTeV Perturbative and
  Non-perturbative QCD (Uses CDF or DØ detectors as
  core)
• Running BTeV 30M/yr, GTeV concurrently a little
  extra
• Add precision forward and very forward tracking,
  upgraded data acquisition and perhaps forward
  calorimetry, perhaps 10M

Primary Goal Understand Strong Interactions
Tevatron as a Tagged Gluon Collider
tag proton and anti-proton, have a gluon
collider Gluon density g(x, kT, Q2) at
very low x saturation, unitarity,
non-perturbative frontier Pure Gluon jets
fragmentation, color connection
Determine glueball spectrum
missing mass resolution of 100 MeV
Measure exclusive Relates to SM
Higgs study at LHC Discover new exotic
hadrons Hybrids, 4-quark, 5-quark,
... !? Search for exotics
CP-odd H (SUSY), radions, gluinoballs, etc.

GTeV Plans

• LOI for Spring 2005 PAC
• Convenors
• Physics Fred Olness (SMU)Mark Strikman (Penn
  St.)
• MC Brian Cox (Manchester)
• Tevatron Mike Martens (FNAL)Yuri Alexahin
  (FNAL)
• Forward Detectors Rick Tesarek (FNAL) Helio da
  Motta (CBPF)
• Studying technical issues (critical path is high
  field dipole to create warm space) can we build
  a collaboration?

My Opinion

• Solid physics program, needs refinement
• Makes sense to have a second experiment
• Need U.S. experimental alternatives to LHC
• Training of new GTeV experts will help offset LHC
• drain in 2007-2009
• Need 5-10 of CDF/ DØ people from HERA, fixed
  target, Jlab, etc. to be viable
