Nuclear ρ meson transparency in a relativistic Glauber model
Background: The recent Jefferson Laboratory data for the nuclear transparency in rho(0) electroproduction have the potential to settle the scale for the onset of color transparency (CT) in vector meson production. 
Purpose: To compare the data to calculations in a relativistic and quantum-mechanical Glauber model and to investigate whether they are in accordance with results including color transparency given that the computation of rho-nucleus attenuations is subject to some uncertainties. 
Method: We compute the nuclear transparencies in a multiple-scattering Glauber model and account for effects stemming from color transparency, from rho-meson decay, and from short-range correlations (SRC) in the final-state interactions (FSI). 
Results: The robustness of the model is tested by comparing the mass dependence and the hard-scale dependence of the A(e, e'p) nuclear transparencies with the data. The hard-scale dependence of the (e, e', rho(0)) nuclear transparencies for C-12 and Fe-56 are only moderately affected by SRC and by rho(0) decay. 
Conclusions: The RMSGA calculations confirm the onset of CT at four-momentum transfers of a few (GeV/c)(2) in. meson electroproduction data. A more precise determination of the scale for the onset of CT is hampered by the lack of precise input in the FSI and rho-meson decay calculations.
