Seq. Number (TBA ) Research Plan at RIKEN CC-J Date: 08/Jan/2003 To: the Planning and Coordination Office of RIKEN CC-J Reseach Subject : E325 DST production Person responsible for this reserch: Name : R.

Muto Tel/Fax : x3296 E-mail : muto@nh.scphys.kyoto-u.ac.jp ---------------------------------------------------------------- Summary of this research (10-100 lines) KEKPS E325 is an experiment that measure the vector meson decay in nuclei to explore the partial restoration of the chiral symmetry of QCD. We intend to analysis the data taken in 2002 and 2001 ( about 2.3TB of raw data ) with improved calibration parameters of drift chambers and magnetic field. We had already got some hints about rho and phi meson mass modifications in nuclear matter. With this DST production, we will be able to discuss these modifications more precisely. Estimated CPU time required : 15 x 150 x24 hours (with Pentium III 850MHz) Estimated disk space usage required : 1000 GB(working space) Estimated HPSS space usage required : 2000 GB (produced DST) Target date for completion : 31/01/2003 (DD/MM/YY) --------------------------------------------------------------------------- ML archives: http://www.rarf.riken.go.jp/rarf/rhic/ml/nmlist/phenix-ccj-pco/
