Summary of this research (5-10 lines)
We measure low-mass vector mesons, omega and phi, via di-electron decay
channel in PHENIX.
This is the best probe of chiral symmetry restoration in hot matter created
by heavy ion collision.
Some model calculations predict in-medium modifications of the vector
mesons.
We measure these mass spectra and yield using the PHENIX central
spectrometer.
We need some disk and CPU time for experimental and simulation data.


Estimated CPU time required : 1,000 hours (with Pentium III 1GHz)
Estimated disk space usage required : 1,000 GB
Estimated HPSS space usage required : 2TB
HPSS band width for above estimate  :  - MB/s
Target date for completion (cpu) : 31/12/11 (DD/MM/YY)
                       (disk):  31/03/12
