The quenched SU(2) scalar-gluon vertex in minimal Landau gauge
arXiv:1902.10568 · doi:10.1103/PhysRevD.99.114503
Abstract
The question of whether confining effects are visible in correlation functions is a long-standing one. Complementing investigations on the propagators of fundamental and adjoint scalar matter particles here the quenched scalar-gluon vertex is investigated. For this purpose a multitude of lattice setups in two, three, and four dimensions is analyzed in quenched SU(2) lattice gauge theory. Though both cases are quantitatively different, neither a qualitative difference nor any singularities are observed.
