This proposal includes three topics for investigation, in the framework of overlapfermions. These topics are:(i) QCD in the large N limit, The PI has made very important contributions to thedevelopment of the overlap method to deal with chiral fermions in lattice field theory.The present proposal is to implement this method in lattice QCD in the limit of a largenumber of colors. This work is technically very challenging and will lead to a betterunderstanding of theoretical and computational issues surrounding chiral fermions andlarge N QCD.(ii) Chiral symmetry breaking in QCD, and (iii) Cancellation of gauge anomalies in chiral gauge theories.

这个建议包括三个主题的调查，在的框架内，费米子。（i）大N极限下的QCD，PI对格点场论中手征费米子的重叠方法的发展做出了重要贡献，本文提出在大色数极限下的格点QCD中实现这一方法。这项工作在技术上是非常具有挑战性的，并将导致更好地理解周围的手征费米子和大N量子色动力学的理论和计算问题。(ii)QCD中的手征对称破缺，以及（iii）手征规范理论中规范反常的抵消。
