PPR Purpose Timeline PPR Physics Performance Report Ostensibly

PPR: Purpose, Timeline • PPR = “Physics Performance Report” – Ostensibly, a document indicating readiness for data-taking – for the p-p program Þ 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. Þ We won’t be taking heavy ion data in 2007 Þ We are behind in developing analysis tools – But: we cannot relax 9/24/2020 Heavy Ion PPR Thoughts 1

PPR Straw-man Outline 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 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 9/24/2020 Heavy Ion PPR Thoughts 2

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 1 st 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 highstatistics Monte-Carlo samples. – Need to get started on validating CSC samples 9/24/2020 Heavy Ion PPR Thoughts 3

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 9/24/2020 Heavy Ion PPR Thoughts 4

Technical Issues/Hurdles • Need to make progress on developing heavyion analysis tools, ESD/AOD output – Even simple results like Multiplicity, ET, … – And corresponding truth quantities Þ e. g. we should be trying to define data structures Þ 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. 9/24/2020 Heavy Ion PPR Thoughts 5
