Non-perturbative evaluation for anomalous dimension in 2-dimensional O(3) sigma model
Sergio Calle Jimenez, Makoto Oka, Kiyoshi Sasaki
We calculate the wave-function renormalization in 2-dimensional O(3) sigma model, non- perturbatively. It is evaluated in a box with a finite spatial extent. We determine the anoma…
Scattering lengths for two pseudoscalar meson systems
Kiyoshi Sasaki, Naruhito Ishizuka, Makoto Oka +1
Scattering lengths for two pseudoscalar meson systems, , and , are calculated from lattice QCD by using the finite size formula. We perform the…
S-wave pi-K scattering length from lattice QCD
Kiyoshi Sasaki, Naruhito Ishizuka, Takeshi Yamazaki +2
The -wave scattering lengths are calculated for both the isospin 1/2 and 3/2 channels in the lattice QCD by using the finite size formula. We perform the calculation with $…
I=2 Two-Pion Wave Function and Scattering Phase Shift
Kiyoshi Sasaki, Naruhito Ishizuka
We calculate a two-pion wave function for the I=2 -wave two-pion system with a finite scattering momentum and estimate the interaction range between two pions, which allows us t…
Finite Size Effect in Excited Baryon Spectroscopy
Kiyoshi Sasaki, Shoichi Sasaki
We investigate the finite size effect on masses of excited baryons in quenched lattice QCD simulation. For this purpose, we perform numerical simulations at three different lattice…
Spectral Analysis of Excited Nucleons in Lattice QCD with Maximum Entropy Method
Kiyoshi Sasaki, Shoichi Sasaki, Tetsuo Hatsuda
We study the mass spectra of excited baryons with the use of the lattice QCD simulations. We focus our attention on the problem of the level ordering between the positive-parity ex…
