Description

Lattice gauge theories with gauge groups SO(3) and SU(2) are compared. The free energy of electric twist, an order parameter for the confinement-deconfinement transition, is measured in both theories. A mysterious phase with negative adjoint Polyakov loop found in SO(3) is explained. The relevance for confinement of the centre of the gauge group is discussed.
