Preliminary Results on Photoproduced Transparency of the ρ0 Meson at Jefferson Lab Hall D

The experiment E12-19-003, conducted at Jefferson Lab’s Hall D in 2021, aimed to investigate the predicted QCD phenomenon known as color transparency through photoproduction of vector mesons from nuclear targets (deuterium, helium, and carbon). In this presentation, I will report preliminary measurements of photoproduced nuclear transparency for the ρ⁰ meson. Improved background subtraction methods were applied to enhance signal purity in the ρ⁰ meson reconstruction. The resulting transparency ratios, measured across different nuclear targets as a function of momentum transfer ∣t∣(GeV²), will be presented.
