SU(3) breaking effects in hyperon beta decay from lattice QCD
Shoichi Sasaki, Takeshi Yamazaki
We present results of an exploratory study of flavor SU(3) breaking effects in hyperon beta decays using domain wall fermions. From phenomenological point of view, the significance…
Signatures of S-wave bound-state formation in finite volume
Shoichi Sasaki, Takeshi Yamazaki
We discuss formation of an S-wave bound-state in finite volume on the basis of Lüscher's phase-shift formula.It is found that although a bound-state pole condition is fulfilled onl…
Charmonium properties in deconfinement phase in anisotropic lattice QCD
H. Iida, T. Doi, N. Ishii +2
J/Psi and eta_c above the QCD critical temperature T_c are studied in anisotropic quenched lattice QCD, considering whether the c\bar c systems above T_c are spatially compact (qua…
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…
Excited Baryon Spectroscopy from Lattice QCD: Finite Size Effect and Hyperfine Mass Splitting
Kiyoshi Sasaki, Shoichi Sasaki
A study of the finite-size effect is carried out for spectra of both ground-state and excited-state baryons in quenched lattice QCD using Wilson fermions. Our simulations are perfo…
