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

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)

Progress?

Page 6: ALICE Physics Selection  Quality Assurance

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
