Description

We discuss the physics of 2-dimensional QCD with adjoint fermion content. Unexpectedly, in the case when the fermions are massless and the gauge group is SU(N) with even N, they can screen a heavy probe charge even if it belongs to the fundamental color representation. If N is odd, the situation is not so clear. In the old paper of Gross, Klebanov, Matitsyn and myself, we argued that the theory is screening also in this case. However, this conclusion was contested in the recent paper by Cherman, Jacobson, Tanizaki and Unsal. There are also some fresh developments in understanding this phenomenon, which I will discuss in my talk.
