WebChiral Perturbation Theory: a Primer Barry R. Holstein Department of Physics and Astronomy University of Massachusetts Amherst, MA 01003 and Institute for Nuclear Theory, NK-12 University of Washington Seattle, WA 98195 Abstract Recently methods have been developed which exploit the chiral symmetry of QCD in WebAug 30, 2024 · Idea 0.1. In the context of the 't Hooft double line construction and the AdS/CFT correspondence with N_c \in \mathbb {N} colors, the small N region or large 1/N_c limit is the situation away from the large N limit. In this large 1/N_c limit perturbative string theory -corrections (for small 't Hooft coupling \lambda = g_ {YM}^2 N_c) and/or M ...
