Description
We study numerically the phase structure in two dimensions
with SU(2) gauge-Higgs coupling.
We calculate the static potential from Wilson Loop, W propagator
and the order parameter related to a transition between the confinement-like
phase and Higgs-like phase. Our results suggest that there
is a confinement-like phase and Higgs-like phase, even in two dimensions.
In the confinement-like phase, the static potential rises linearly with string breaking at large distances, while in the Higgs-like phase, it is of Yukawa
type, consistent with a Higgs-type mechanism. The correlation length
obtained from the W propagator has a maximum between these phase.
