Outline of Final Research Achievements |
The lattice QCD calculation of matrix element to reveal the flavor structure of nucleon is difficult due to operator mixings from UV divergence, so that a new renormalization method on the lattice is needed . We study the renormalization of new operators based on the flow equation, We showed that the field flowed is finite at next-to-leading order in 1/N for 3d O (N) scalar theory. Moreover, there is a close relation with AdS / CFT correspondence that the spacetime defined by induction metering approaches the AdS spacetime near the fixed point.
