Description
The recent measurements of exclusive backward-angle meson electroproduction
from Jefferson Lab hint at a new domain of applicability of the QCD collinear
factorization framework in the special u-channel kinematics regime. As a
signature of QCD degrees of freedom in nuclei, and as a co-requisite of
reaching the factorization regime, Color Transparency is expected to manifest
itself as an increase in nuclear transparency with increasing momentum
transfer. With the most recent quasi-elastic C(e,e'p) data ruling out Color
Transparency up to Q^2=14.2 (GeV/c)^2, looking for CT in u-channel kinematics
has became a topic of debate within the nuclear physics community. In this
presentation, we present an idea that will attempt to test color transparency
using a u-channel pi0 electroproduction process: A(e,e'p)pi0.
