1. PPR: Purpose, Timeline PPR = “Physics Performance Report”
Ostensibly, a document indicating readiness for data-taking – for the p-p program
Including trigger performance
Produced using current CSC simulations & analysis from results in the CSC notes.
Heavy ion PPR
Purpose will be the same: readiness for data
Deadline will probably be decided by us.
We won’t be taking heavy ion data in 2007
We are behind in developing analysis tools
But: we cannot relax

2. PPR Straw-man Outline Caveat: this has not been discussed with Laurent
Physics overview
Detector Performance & Reconstruction
Minimum-bias, Centrality, Event properties
Single particle spectra
Single jets & jet fragmentation
Di-jets & gamma/Z-jet
Quarkonia
Open heavy flavor
Low-x measurements
Ultra-peripheral collisions
Caveat: this has not been discussed with Laurent

3. PPR: Where do we stand?
We have a tremendous amount of work to do to prepare any one of these sections.
Unfeasible to consider PPR deadline sooner than 6 months from now.
6 months reasonable for 1st draft?
But, PPR will provide useful focus for our simulation and analysis efforts.
Organize our own efforts around PPR sections
We will have to rely on the CSC for high-statistics Monte-Carlo samples.
Need to get started on validating CSC samples

4. PPR Organization
Clearly we are going to need people to take responsibility for organizing sections
Outline
Defining content
Organizing effort to produce that content
Keeping track of progress
PPR will provide a valuable tool for organizing our effort all the way to physics.
Clearly: getting PPR organization started is the highest priority for convenors.
It is ~ official that I will become convenor.
As soon as Laurent is notified, I will start on

5. Technical Issues/Hurdles
Need to make progress on developing heavy-ion analysis tools, ESD/AOD output
Even simple results like Multiplicity, ET, …
And corresponding truth quantities
e.g. we should be trying to define data structures
This will help focus analysis efforts
Need to start studying level-1 output in ESD & AOD for trigger studies
Need to adopt common analysis model for short & intermediate term.
Need to work out heavy-ion specific issues in tracking.
