  1. Criteria for Tevatron Runningin FY 2010 Pier Oddone September 24, 2007

  2. Criteria for running in 2010 • Important Physics • Viable Collaborations • Acceptable damage to other programs

  3. Important Physics • We explore uniquely a large variety of physics at the energy frontier until LHC detectors overtake us • Sensitivity to ~160 GeV Higgs at 95% CL, opens in the next year • Low mass Higgs (Standard or lowest lying MSSM Higgs below 150 GeV) is hard to reach early with the LHC

  4.

  5. LEP Tevatron LHC only excl. LHC SM Higgs Searches

  6. Constraint MSSM (CMSSM) With Electroweak precision measurements and cold dark matter density (WMAP, …) Sven Heinemeyer, Georg Weiglein

  7. Run II 2009 W and Top Mass, and SM Higgs Will Tevatron’s prediction and observation/exclusion agree with what LHC sees?

  8. LP2007 Tevatron Expected Tevatron Observed SM Higgs Searches at Tevatron

  9. Important Physics • From first collisions at the LHC in Summer 2008 and closure of Tevatron September 2009 is too short for LHC detectors to wipe CDF/D0 out • Any delay in putting the hardware together – no float now • Delay in first beam to collisions – only three months now • Natural time to accumulate luminosity • Debugging detector and software • Physics analysis

  10. Viable Collaborations • The collaborations should be viable through FY2009 • To ensure collaborations are viable in FY2010, we need to start working now to make sure there are enough students/post-docs and “know how” • Early results from LHC could negatively impact the collaborations in 2010 if most folks were to decamp Should we be so lucky!!

  11. Viable Collaborations • Conversely, if there are delays in getting results from LHC, the Tevatron remains exciting, producing physics for students/postdocs/faculty • In the middle, there could be a horse race to the Higgs • To keep collaborations viable need agency support of University groups for work at the Tevatron beyond 2010

  12. Acceptable damage • Running in 2010 delays 700kW neutrino beam • Running in 2010 has modest impact on NOvA start-up (presently shut-down starts late 2010; physics run June 2011) • Requires additional resources not to slow down the ILC R&D, Project X, or neutrino program; approximately $30M

  13. Conclusion • We believe strongly that DOE should plan to run through FY2010 • An early recommendation by P5 would help the planning effort for the lab and collaborations.
