Presentation Transcript

  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 Heavy Ion PPR Thoughts

  2. PPR Straw-man Outline • 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 Heavy Ion PPR Thoughts

  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 Heavy Ion PPR Thoughts

  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 Heavy Ion PPR Thoughts

  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.
