1. N Ω dibaryon from lattice QCD near the physical point / Iritani, Takumi ; Aoki, Sinya ; Doi, Takumi ; Etminan, Faisal ; et al
The nucleon( N )-Omega(Ω) system in the S-wave and spin-2 channel ( S25 ) is studied from the (2+1)-flavor lattice QCD with nearly physical quark masses ( mπ≃146MeV and mK≃525MeV ). [...]

2. Consistency between Lüscher’s finite volume method and HAL QCD method for two-baryon systems in lattice QCD / Iritani, Takumi ; Aoki, Sinya ; Doi, Takumi ; Hatsuda, Tetsuo ; et al
There exist two methods to study two-baryon 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 non-local potential associated with the tempo-spatial correlation function. [...]

10. 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 non-invariant states as well. [...]
