The goal of the analysis is to obtain A_LL of jet production as a function of pT_cone, which is defined as the sum of pT of photons and charged particles in cone around high-pT trigger photon. The pT_cone is a fraction of pT of jet, and the relation between pT_cone and pT of jet is evaluated with PYTHIA event generator and PISA detector simulator. Estimated CPU time required : 0 hours () Estimated disk space usage required : 150 GB Estimated HPSS space usage required : 70 GB HPSS band width for above estimate : MB/s Target date for completion (cpu) : / / (DD/MM/YY) (disk): 12/31/07 Plan for the publication of this result (if possible) Other useful infomation The simulation needed in this analysis for PHENIX Run3 data has been submitted and completed. The data size of the simulation was 40 GB and is increasing gradually due to detailed analyses. In addition, we plan to execute a simulation for PHENIX Run5 data, which will need a disk space comparable with the simulation for PHENIX Run3 data. Therefore We would request the 150 BG disk space.
