The system in the channel (the most strange dibaryon)
is studied on the basis of the (2+1)-flavor lattice QCD simulations with a
large volume (8.1 fm) and nearly physical pion mass MeV
at a lattice sp...

Euclidean two-point correlators of the energy-momentum tensor (EMT) in SU(3)
gauge theory on the lattice are studied on the basis of the Yang-Mills gradient
flow. The entropy density and the specific heat obtained from the two-point
correlators ar...

A sanity check rules out certain types of obviously false results, but does
not catch every possible error. After reviewing such a sanity check for
bound states with the Lüscher's finite volume formula[1-3], we give further
evidences for th...

On the basis of the Lüscher's finite volume formula, a simple test
(consistency check or sanity check) is introduced and applied to inspect the
recent claims of the existence of the nucleon-nucleon () bound state(s) for
heavy quark masses in...

The strangeness baryon-baryon interaction is investigated directly
from the fundamental theory of the strong interaction, QCD. The HAL QCD method
enables us to extract baryon interactions from the Nambu-Bethe-Salpeter wave
functions without...
