Diquark mass and quark-diquark potential by lattice QCD using an extended HAL QCD method with a static quark
Kai-Wen Kelvin-Lee, Noriyoshi Ishii
We will calculate the diquark mass together with the quark-diquark potential. We apply an extended HAL QCD potential method to a baryonic system made up from a static quark and a d…

Axialvector diqaurk Mass and quark-diquark potential in Sigma_c
Soya Nishioka, Noriyoshi Ishii
The axialvector diquark is studied by using 2+1 flavor Lattice QCD. Being a two-quark object, diquark has a non-neutral color charge. Hence the two-point correlators of diquark fie…

Gauge Dependence of ccbar Potential from Nambu-Bethe-Salpeter Wave Function in Lattice QCD
Tianchen Zhang, Noriyoshi Ishii
We study the gauge dependence of potentials extracted from Nambu-Bethe-Salpeter (NBS) wave functions. The potentials are obtained using the HAL QCD potential method, wit…
