Consistency between Lüscher's finite volume method and HAL QCD method for two-baryon systems in lattice QCD
Takumi Iritani, Sinya Aoki, Takumi Doi +6
There exist two methods to study two-baryon systems in lattice QCD: the direct method which extracts eigenenergies from the plateaux of the temporal correlator and the HAL QCD meth…
Linear confinement and stress-energy tensor around static quark and anti-quark pair -- Lattice simulation with Yang-Mills gradient flow --
Ryosuke Yanagihara, Takumi Iritani, Masakiyo Kitazawa +2
We study the spatial distribution of the stress tensor around static quark-anti-quark pair in SU(3) lattice gauge theory. In particular, we reveal the transverse structure of the s…
dibaryon from lattice QCD near the physical point
Takumi Iritani, Sinya Aoki, Takumi Doi +8
The nucleon()-Omega() system in the S-wave and spin-2 channel (S) is studied from the (2+1)-flavor lattice QCD with nearly physical quark masses (~MeV…
QCD Sum Rule for Open Strange Meson in Nuclear Matter
Taesoo Song, Tetsuo Hatsuda, Su Houng Lee
The properties of open strange meson in nuclear matter are estimated in the QCD sum rule approach. We obtain a relation between the in-medium mass and width of ($…
Systematics of the HAL QCD Potential at Low Energies in Lattice QCD
Takumi Iritani, Sinya Aoki, Takumi Doi +7
The interaction in the S channel is studied to examine the convergence of the derivative expansion of the non-local HAL QCD potential at the next-to-next-to-leading or…
Distribution of Stress Tensor around Static Quark--Anti-Quark from Yang-Mills Gradient Flow
Ryosuke Yanagihara, Takumi Iritani, Masakiyo Kitazawa +2
The spatial distribution of the stress tensor around the quark--anti-quark () pair in SU(3) lattice gauge theory is studied. The Yang-Mills gradient flow plays a crucial…
