Abelian-Higgs phase of SU(2) QCD and glueball energy |
|
| Authors: | JIA Duojie |
| Abstract: | It is shown that SU(2) QCD admits an dual Abelian-Higgs phase, with a Higgs vacuum of a type-Ⅱ superconductor. This is done by using a connection decomposition for the gluon field and the random-direction approximation. Using a bag picture with soft wall, we presented a calculational procedure for the glueball energy based on the recent proof for wall-vortices Nucl. Phys. B 741(2006)1]. |
