Search for the Onset of Color Transparency : JLab E02-110 experiment
ORAL
Abstract
The JLab E02-110 experiment was carried out in 2003-2004 using the CEBAF Large Acceptence Spectrometer (CLAS) located in Hall B at Jefferson Laboratory. The main goal of this experiment is to look for the onset of Color Transparency (CT) in the exclusive incoherent $\rho^{0}$ electroproduction on deuterium, carbon and iron. These measurements study the $Q^{2}$ dependence of the nuclear transparency $T_{A}$, the ratio of the nuclear per-nucleon ($\sigma _{A}/A$) to the free nucleon ($\sigma _{N}$) cross sections, at fixed coherence length $l_{c}$ of quark-antiquark fluctuations of the virtual photon. A significant increase of $T_{A}$ with $Q^{2}$ would be a signature of CT. A brief description to the experiment and the ongoing analysis work will be presented in this talk.
