Effective Abelian-Higgs Theory from SU(2) gauge field theory
In the present work we show that it is possible to arrive at a
Ginzburg-Landau (GL) like equation from pure SU(2) gauge theory. This has a
connection to the dual superconducting model for color confinement where color
flux tubes permanently bind quarks into color neutral states. The GL Lagrangian
with a spontaneous symmetry breaking potential, has such (Nielsen-Olesen) flux
tube solutions. The spontaneous symmetry breaking requires a tachyonic mass for
the effective scalar field. Such a tachyonic mass term is obtained from the
condensation of ghost fields.Comment: 7 pages, 0 figures. Based on talk given at DPF200
