Concretely, we compute by numerical simulations this operator in the (2+1)-dimensional Z(2) lattice gauge theory (LGT) with Z(2) gauge fields coupled to Z(2)-valued Higgs fields. While we cannot provide an unambiguous evidence, we present some hints that the Fredenhagen-Marcu operator is capable of distinguishing the deconfinement phase from the Higgs and confinement phases of the theory.
