The Static Potential in the SU ( 2 ) Higgs Model
The static potential in the confinement “phase” of the SU(2) Higgs model is studied. In particular, the observation of the screening (called string breaking) of the static quarks by the dynamical light quarks leading to the formation of two static-light mesons was not observed before my work in non-Abelian gauge theories. The tool that I employ is lattice gauge simulation. The observable from w...
متن کاملStatic Potential in the Su(2) Higgs Model *
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 r b ≈ 1.8r0, 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.
متن کاملStatic Potential in the SU(2)-Higgs Model and the Electroweak Phase Transition
We present a one-loop calculation of the static potential in the SU(2)-Higgs model. The connection to the coupling constant definition used in lattice simulations is clarified. The consequences in comparing lattice simulations and perturbative results for finite temperature applications are explored.
