Abstract

Evidence for a modification of the ρ⁰ mass in the nuclear medium via the ³He(γ,π⁺π⁻) X reaction is reported here. The tagged photon energies were mostly below the ρ⁰ production threshold on a free nucleon, and the bound nucleon’s Fermi momentum was utilized to produce the. The mass shift observed is δ_mρ⁰=160±35MeV/c² and is significantly larger than theoretical model predictions for this nucleus and nuclear matter density.
