A Non-perturbative Estimate of Vacuum Polarization in QED
Y. M. Cho, D. G. Pak
We present a new estimate of the fine structure constant and the -function of QED at an arbitrary scale. Using the non-perturbative but convergent series expression of the one l…

Dynamical Symmetry Breaking and Magnetic Confinement in QCD
Y. M. Cho, D. G. Pak
We present a gauge independent method to construct the effective action of QCD, and calculate the one loop effective action of QCD in an arbitrary constant background field…
