Gauge Invariance and Stability of SNO vacuum in QCD
Y. M. Cho
We point out a critical defect in the calculation of the functional determinant of the gluon loop in the Savvidy-Nielsen-Olesen (SNO) effective action. We prove that the gauge inva…
Analytic Electroweak Dyon
Y. M. Cho
We present analytic monopole and dyon solutions whose energy is fixed by the electroweak scale. Our result shows that genuine electroweak monopole and dyon could exist whose mass s…
Stability of Monopole Condensation in SU(2) QCD
Y. M. Cho, M. L. Walker
We propose to resolve the controversy regarding the stability of the monopole condensation in QCD by calculating the imaginary part of the one-loop effective action perturbatively.…
Electroweak Knot
Y. M. Cho
We demonstrate the existence of stable knot solitons in the standard electroweak theory whose topological quantum number is fixed by the Chern-Simon index of the bos…
Effective Lagrangian with valence gluons in extended SU(2) QCD model
Y. M. Cho, Haewon Lee, D. G. Pak
The effective action with homogeneous valence (off-diagonal) gluons as background fields in the extended SU(2) model of QCD is obtained in one-loop approximation. We keep the manif…
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…
