Chiral Symmetry Breaking without Bilinear Condensates, Unbroken Axial Z_N Symmetry, and Exact QCD Inequalities
Ian I. Kogan, Alex Kovner, M. A. Shifman
An alternative pattern of the chiral symmetry breaking, suggested recently by Stern, is investigated. It could be self-consistent provided that the chiral …

Heavy flavor decays, OPE and duality in two-Dimensional 't Hooft model
I. Bigi, M. Shifman, N. Uraltsev +1
The 't Hooft model (two-dimensional QCD in the limit of large number of colors) is used as a laboratory for exploring various aspects of the heavy quark expansions in the nonlepton…
