Description
The photoproduction of vector mesons on various nuclei has been studied using the Cebaf Large Acceptance Spectrometer (CLAS) at Jefferson Laboratory. The ρ, ω, and φ mesons are observed via their decay to e+e-. The ρ spectral function is extracted from the data on carbon, iron, and titanium. We observe no effects on the mass of the ρ meson, some widening in titanium and iron is observed consistent with standard collisional broadening
