En'yo, S. Yokkaichi, T. Tabaru, M. Naruki, R. Muto Summary of this research (10-100 lines) The experiment E325 has been performed at the KEK proton synchrotoron to measure the invariant mass spectra of rho, omega and phi mesons through their e+e- or K+K- decays in 12 GeV p+A interactions. The data acquisition was completed in March 2002, and we have observed in-medium modification of the rho and/or omega mesons at normal nuclear-matter density. In this research, we study the vector meson mass modification using phi -> K+K- channel. To analyze kaon data, we need large disk space to put final-kaonDST which were generated before. And to make ntuples, we need CPU time below. 0.7(h/job) * 1000(job) * 4 = 2800(h) Estimated CPU time required : 2800 hours (with Pentium III 1GHz) Estimated disk space usage required : 500 GB Estimated HPSS space usage required : 0 GB HPSS band width for above estimate : 0 MB/s Target date for completion (cpu) : 22/10/05 (DD/MM/YY) (disk): 22/10/05 Plan for the publication of this result (if possible) Other useful infomation
