Static potential in the SU(2) Higgs model
Abstract
We present results for the static potential in the confinement phase of the SU(2) Higgs model on the lattice. Introducing a suitable matrix correlation function we observe string breaking at a distance rb ~ 1.8 r0, where the length scale r0 has a value r0 ~ 0.5 fm in QCD. The method presented here may lead the way towards a treatment of string breaking in QCD.
