抄録

The experiment E325 has been carried out at KEK-PS to investigate nuclear media effects on the invariant mass spectra of ρ, ω and φ mesons through their decays in the e+ e- or K+ K - channels. From the earlier data, the experiment has reported the signature of in-medium mass modification of ρ and/or ω mesons for the first time. This manuscript describes our preliminary results based on the data aquired in the allocated beam time of ∼3200 hours, which ended in February 2002.
