N= 1超级Yang-Mills （SYM）理论的大N极限与具有反对称表示的费米子的QCD变体之间的平面等价是获得QCD本身解析性非微扰结果的有力工具。特别是，它允许从N= 1 SYM中的胶子凝聚的精确计算中推断出具有基本表示的N= 3 QCD中的夸克凝聚。在本文中，我们回顾和完善了我们之前对具有一般数目N f的QCD中的夸克凝聚的预测，并与晶格结果进行了比较。
Planar equivalence between the large N limits of N= 1 Super Yang–Mills (SYM) theory and a variant of QCD with fermions in the antisymmetric representation is a powerful tool to obtain analytic non-perturbative results in QCD itself. In particular, it allows the quark condensate for N= 3 QCD with quarks in the fundamental representation to be inferred from exact calculations of the gluino condensate in N= 1 SYM. In this paper, we review and refine our earlier predictions for the quark condensate in QCD with a general number n f of flavours and confront these with lattice results.
