String breaking and lines of constant physics in the SU(2) Higgs model

Abstract

We present results for the ground state and first excited state static potentials in the confinement "phase" of the SU(2) Higgs model. String breaking and the crossing of the energy levels are clearly visible. We address the question of the cut-off effects in our results and observe a remarkable scaling of the static potentials.Comment: LATTICE99(Higgs), 3 pages, 4 figure
