Consistency between Lüscher’s finite volume method and HAL QCD method for twobaryon systems in lattice QCD
/ Iritani, Takumi ; Aoki, Sinya ; Doi, Takumi ; Hatsuda, Tetsuo ; et al
There exist two methods to study twobaryon systems in lattice QCD: the direct method which extracts eigenenergies from the plateaux of the temporal correlation function and the HAL QCD method which extracts observables from the nonlocal potential associated with the tempospatial correlation function.

Most Strange Dibaryon from Lattice QCD
/ Gongyo, Shinya ; Sasaki, Kenji ; Aoki, Sinya ; Doi, Takumi ; et al
The $\Omega \Omega $ system in the ${}^{1}{S}_{0}$ channel (the most strange dibaryon) is studied on the basis of the ($2+1$)flavor lattice QCD simulations with a large volume $(8.1\text{}\text{}\mathrm{fm}{)}^{3}$ and nearly physical pion mass ${m}_{\pi}\simeq 146\text{}\text{}\mathrm{MeV}$ at a lattice spacing of $a\simeq 0.0846\text{}\text{}\mathrm{fm}$.

On the definition of entanglement entropy in lattice gauge theories
/ Aoki, Sinya ; Iritani, Takumi ; Nozaki, Masahiro ; Numasawa, Tokiro ; et al
We focus on the issue of proper definition of entanglement entropy in lattice gauge theories, and examine a naive definition where gauge invariant states are viewed as elements of an extended Hilbert space which contains gauge noninvariant states as well. [...]
