Nuclear force with LapH smearing
Takuya Sugiura, Yutaro Akahoshi, Tatsumi Aoyama +2
The nuclear forces are determined by combining the HAL QCD method and a new type of source smearing technique. The new smearing is a projection to a space spanned by the lowest-lyi…
Dibaryon with highest charm number near unitarity from lattice QCD
Yan Lyu, Hui Tong, Takuya Sugiura +5
A pair of triply charmed baryons, , is studied as an ideal dibaryon system by (2+1)-flavor lattice QCD with nearly physical light-quark masses and the relativistic…
Lattice QCD Study of the Nucleon-Charmonium Interaction
Takuya Sugiura, Yoichi Ikeda, Noriyoshi Ishii
The -nucleon interaction is studied by lattice QCD calculations. At the leading order of the derivative expansion, the interaction consists of four terms: the central, the spi…
Charmonium-nucleon interactions from 2+1 flavor lattice QCD
Takuya Sugiura, Yoichi Ikeda, Noriyoshi Ishii
The charmonium-nucleon interaction is studied by the time-dependent HAL QCD method. We use a larger lattice volume and the relativistic heavy quark action for charm quark to obtain…
Properties of non-local wave function equivalent potential with generalized derivative expansion
Takuya Sugiura, Keiko Murano, Noriyoshi Ishii +1
We examine the properties of the wave-function-equivalent potentials which HAL QCD collaboration has introduced. We generalize the derivative expansion, and then apply it to energy…
