Investigating the onset of color transparency with CLAS
Quantum Chromo Dynamics (QCD) predicts that point-like colorless systems will exhibit vanishingly small cross-sections and are thus expected to travel through the nucleus with little attenuation, a phenomenon known as Color Transparency (CT). An increase in nuclear transparency, $$T_A$$, for increasing momentum transfer, $Q^2$, would signal the onset of CT. We present an experiment with the CLAS detector on exclusive incoherent electro-production on nuclei of the $$\rho^0$$ meson, which is a particularly sensitive reaction to study CT. Preliminary results of this experiment show a clear rise in $$T_A$$ with increasing $Q^2$, indicating the onset of Color Transparency.
