## P5

- The final report of the P5 Committee: "The Particle Physics Roadmap” is out and available on the HEPAP website:
- _http://www.science.doe.gov/hep/hepap_reports.shtm__ _
-  A comprehensive report of great interest to the HEP community
- _http://www.science.doe.gov/hep/P5RoadmapfinalOctober2006.pdf__ _
- It has the Tevatron running through FY09 [as baseline]
- We will still be reviewed in Spring 2007 (April or May)
- Committee will take into account:
- HEP budget situation
- Luminosity
- Staffing
- Overall physics output and Higgs progress

- Last two points are on our court

***CDF  Measurements will continue to improve***

***Pointing to a light SM Higgs***

## The road to the Higgs

## Status Today: 0.3-1.0 fb-1

## Already a long way from Run 1

## Projected Data Sample Growth

- We are here today

- We’ve analyzed this much

## More sensitivity for Higgs

- So we’ll likely get the luminosity, now what?
- NEED TO EXPLOIT EVERY BIT OF SENSITIVITY that we can find:
- 5 x 10% losses ==> our dataset is reduced by x 2  !
- We need to go after as many 5-10% effects as possible
- Better b-tagging overall
- Forward tracking and forward b-tagging
- Include all lepton types with maximal efficiency
- Improve Jet E resolution, B-jet E resolution
- Better use of existing triggers
- Trigger upgrades
- Open trigger to include maximum searchable phase space
- Improve analysis techniques
-  ALL THESE EFFORTS ARE UNDER WAY...

## Ex: Forward Tracking

- !

- Not yet in Higgs analyses

## Ex: Better b-tagging (aka über-tagger)

- Blessed ~ 1 month ago - not yet in Higgs analyses

- !

## Ex: Forward B-tagging

- Not yet in Higgs analyses

## Ex: BMU muons

- !

- Not yet in Higgs analyses

## Ex: Improving Jet E resolution

- NN: Not yet in Higgs analyses

## Streamlining High-Pt tools

- New ID and Physics Perfomance Coordinator that will provide a common software framework and executable - Simona Rolli
-   it will automatically calculate particle ID, trigger efficiencies, scale factors, JES etc. for a given run range
-   it will incorporate all the relevant pieces of code
-        (already existing or being developed)
-   it will output  lookup tables/ web pages/ scale factors /documentation on the values of different parameters for different run ranges.
-  It will be a natural monitor of offline detector performances (W/Z plots, rates etc ...)
- First implementation expected for March 2007 Winter Conferences

- Muon

- Jets

- B-jets

- ......

- Production ntuples

- Electrons

- Input to analyses

## Improvements from the Trigger

- CRITICAL to open up the trigger maximally
- Control rates at high lum and open up new paths
- XFT stereo upgrade
- L1 achieved  x7-8 fake rejection with 97% efficiency !
- L2 Cal Cluster Upgrade
- Project approved and under way !
- Optimize use of existing triggers

- used

- Exist
- not used

## L2 Calorimeter Cluster Upgrade Project

- Vadim Rusu
- with
- Laura Sartori &
- Gene Flanagan
- In RED are places
- where people are
- Needed NOW

## NEW: Higgs Trigger Task Force (HTTF)

- Forming task force to:
*Propose a comprehensive trigger strategy to optimize our sensitivity for the standard model Higgs boson and related searches*
- Evaluate techniques to further improve our acceptance for Higgs signatures, as well as devising techniques to maintain high acceptance at Tevatron luminosities which may exceed 3x1032 cm-2 s-1.  The Task Force should bring together experts in the detector, trigger, data acquisition system and Higgs search analyses to provide an integrated strategy to maximize our sensitivity
- Beate Heinemann and Kevin Pitts will lead the HTTF

## The Road to the Higgs

## New Higgs Group

- Such an effort will help pull CDF together
- both in spirit and operationally
- Will energize the collaboration
- Many young and talented people have expressed interest in staying to do exactly this
- Many institutions have expressed interest in working on such a broad Higgs effort and are “ready at the gate”
- Maybe our smart and hard work and Nature’s kindness will allow us to discover the elusive Higgs !

## CDF is firing on all cylinders
Detectors and Computing are performing well
Our physics menu is varied and healthy
We have a plan for the “end-game” and we are executing it.
We are publishing our physics in a timely fashion and have had important measurements and discoveries this year. 
For ex: Single-top and W-mass soon
We expect many more before over the next few years as we near the Higgs Horizon...
