  3. ALICE and PSQA • Physics Working Group – Physics Performance (PWG – PP) • Quality Assurance for Physics Selection • Physics Selection applies offline triggers (central part of ALICE data analysis) • Post processing to ensure online trigger is correctly selecting events • Primarily investigating V0, T0, and ZDC triggers • Big Picture: Keeps ALICE running efficiently to gather the best quality data

  4. Problems • Code completely broken from start • Code completely undocumented • With the approvals for Quark Matter, not many chances to clarify questions • Standard frustrations with ROOT • Code now compiles and runs without seg faults (still minor memory corruptions though)

  5. Progress?

  6. Progress? • Remember Newton’s Third Law • Plot may seem nonsensical (which it is), but truly progress has been made Future Goals • Finish optimizing code for new analysis • Interface results with the web, build generic analysis for future QA
