Towards Study of Color Transparency with Medium Energy Electron Beams
Abstract
Description
Interference between vector mesons electroproduced at different longitudinal coordinates leads within Glauber approximation to a $Q^2$-dependence of nuclear effects similar to what is expected to be an onset of color transparency (CT). We suggest such a mapping of the photon energies and virtualities, which eliminates the undesirable $Q^2$-variation and allows to measure a net CT effect. We develop a multichannel evolution equation, which for the first time incorporates CT and the effects of the coherence length in the exclusive electroproduction of vector mesons.
