Description
A central problem of modern physics research is the solution to QCD in the non-perturbative regime. One method of testing QCD in this low-energy region is by measuring certain structure constants of hadrons --- called polarizabilities --- that show particular promise of allowing a direct connection to the underlying quark/gluon dynamics through comparison to modern QCD-inspired model calculations, and to solutions of QCD done computationally on the lattice. This talk will give a status report on our measurement of cross sections for the Primakoff effect using the GlueX detector in Hall D at Jefferson Lab, with the end goal of precise measurements of the pion polarizability for both charged and neutral pions.
