Planar QCD: news from the lattice front

Analytical and numerical methods of lattice field theory have established several facts about planar QCD that eventually should help determine a possible string equivalent: (1) Euclidean planar QCD on an l^4 lattice is l-independent for l>l_c. (2) Chiral symmetry breaks spontaneously by a random matrix mechanism. (3) The pion mass is well described by a parabola in the quark mass.
