Higgs Sensitivity StudyWhat? Why?We were asked by DOE to provide a new estimate/plot (based on data, current understanding of analysis components, new ideas,)Timescale ~ June/July 03 no time for complete analysis!In parallel DOE accelerator review and P5 Run IIb reviewThe message (result and interpretation) should be crisp & clear (+ there is more physics than just Higgs in 2/5/10/15 fb-1)StrategyFormed a CDF/D working group (min overlap with current efforts) (D Members: Babukhadia, Fisher, Goussiou, Klima, Narain, Partridge, Rizatdinova)Use the Run II Working Group study (hep-ph/0010338) as a basisSplit the work wherever possible, e.g. CDF - lnbb, D - nnbb (the most sensitive modes), extrapolate intelligently to all other decay channelsAdd new channels, e.g W/Z(/H?) decaying to t, H WW, and combineThis study may turn out to be important

IntroductionThanks to Jianming for agreeing to serve as a Deputy Physics Coordinator excellent choice, great news (not only to me!)Things Im not going to talk about this timeTrigger Board and Offline Resources Board function very well! interact with many groups, help in planning and implementation, perform nicely under pressure, lively discussions, goal orientedID groups worked extremely hard over the last several months, made great progress on many frontiers, advanced our understanding of the data, interacted well with detector and physics groups, certified objects, always work in progressSorry; no time for more details

Basic requirements (some more crucial than others):Detector and Trigger work adequatelyDecent data-taking efficiency (>75% soon and increasing)Highest priority triggers not prescaledData reconstructed as they are collected (

We should keep the right balance between the need for results to be shown at conferences (+ feedback+ education+ excitement+) and the need for making progress as fast as possible to get to the big prizeHardware/Trigger/Software/AnalysisFind the optimal timing for installation of new hardware/software/triggers, fixing problems, optimization, releases,There is room for improvement Guiding individual effortsCoordination and planningMonitoring of performanceDelivering the goodiesLike any other big organization we are as good as our weakest link The Overall Plan Difficult Decisions

Its very important to have a strong showing

but we have to remember thatthere is future beyond Moriond (LP03, 2004, 2005, ) Goals for Moriond 03 (cont.)message we are beginning to do exciting physics (L~50pb-1)

Boaz Klima

Where is the Physics?

Boaz Klima

With ~50pb-1 @ECM~2TeV we should be able to do interesting physics

But

Our understanding of the data is continuously improving; this is a very complex experimentMany things came in late (data, MC, tmbs, tools, ids,)

Tremendous challenge for the physics groups (24/7) The Challenge

Where are we heading now?

Boaz Klima

Need to add overall goals for the experimente.g. Data-taking efficiency >85%, CTT, TARC, OATF,

Mar. 10 p14 (RECO & MC) ready for the farmsApr. 5 APS/DPF meeting (Philadelphia)May 10 Certified Ids for p14May 31 Certified JES for p14June 11 End of data-taking period for LP03June 27 End of data-processing periodJuly 18 Physics groups approval of resultsAug. 11 Lepton-Photon 2003 @Fermilab Still a tight schedule, but a little better for the end-game (provided we stick to this) The Next Six Months (tentative dates)

Boaz Klima

PublicationsGood enough understanding of our dataImpact on HEP communityWe have a few candidates for this summer

Its time to start thinking about the next several yearsPhysics goals, e.g. W mass, measurements with ts, Higgs,Hardware requirements (performance, stability,)Software/Algorithms needsAnalysis organization & (wo)manpowerComputingDocumentationA nice theme for the summer workshop? Longer-Term Thoughts/Plans

Boaz Klima

ConclusionsExciting physics is just around the corner!Tremendous progress made in many areas over the last several monthsMajor accomplishments; seeds for promising futureWe are seeing signals of all the physics were interested in (so far except for Higgs & NP)We measure cross sections, masses, limits, etcThe next several months (and years!) are going to be very interesting to all of usLets converge on Moriond analyses and get ready to produce even more exciting Physics results in the near future.Just a reminder - this is the most exciting place for HEP research in the next 7 years or so
