The computing and software effort is closely associated with the Physics Working Groups. STAR physics analysis software runs within the context of the computing infrastructure, taking the DST as input. The physics working groups have responsibility for the development of physics analysis software. The STAR Physics Analysis Coordinator acts as coordinator between the PWGs and computing. The PAC's responsibilities are described here.

Rongrong Ma (BNL) is the current STAR Physics Analysis Coordinator.
