• It is a longstanding question whether the confinement of matter fields in QCD has an imprint in the (gauge-dependent) correlation functions, especially the propagators. In particular, in the quenched case, a fundamental difference could be expected between adjoint and fundamental matter. In a preceding investigation, the propagator of a fundamental scalar was studied, showing no obvious sign of confinement. Here, as a complement, the adjoint scalar propagator is investigated over a wide range of parameters in the minimal Landau gauge using lattice gauge theory. This study is performed in two, three, and four dimensions in quenched SU(2) Yang-Mills theory, both in momentum space and position space. No conclusive difference between the two cases is found.
