Description

This talk reviews some recent progress in making sense of confinement. The focus of the talk is on cousins of QCD, rather than QCD itself; these cousin theories have features lacking in QCD which facilitate the analysis. One critical feature of this sort is center symmetry, and the core of the talk is an exploration of the connection of center symmetry to confinement. One principal way to gain insight into this connection is via the study of gauge theories in which matter fields destroy invariance under the full center of the group but preserve a nontrivial subgroup. A second way to gain insight is via a study role of center symmetry in the limit where the number of colors goes to infinity. The large Nc limit is useful as a tool due to its tractability.
