Spectral sum from Euclidean lattice correlators and determination of renormalization constants
Tsutomu Ishikawa, Shoji Hashimoto, Takashi Kaneko
We propose a new method to renormalize lattice operators. The method is based on the technique to compute the spectral sum appearing in the Shifman-Vainshtein-Zakharov QCD sum rule…
Kondo effect with Wilson fermions
Tsutomu Ishikawa, Katsumasa Nakayama, Kei Suzuki
We investigate the Kondo effect with Wilson fermions. This is based on a mean-field approach for the chiral Gross-Neveu model including four-point interactions between a light Wils…
Spectral sum of current correlators from lattice QCD
Tsutomu Ishikawa, Shoji Hashimoto
We propose a method to use lattice QCD to compute the Borel transform of the vacuum polarization function appearing in the Shifman-Vainshtein-Zakharov QCD sum rule. We construct th…
