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…

Domain walls, stabilities, and the mass hierarchy of the Randall-Sundrum Model
Haewon Lee, W. S. l'Yi
Randall-Sundrum model, which has a scalar field, is used to investigate the domain structure of the extra dimension and to obtain a possible solution of the mass hierarchy problem.…

Effective Theory of QCD
Y. M. Cho, Haewon Lee, D. G. Pak
We derive a generalized Skyrme-Faddeev action as the effective action of QCD in the low energy limit. Our result demonstrates the existence of a mass gap in QCD which triggers the…
