ppK- bound states from Skyrmions
Tetsuo Nishikawa, Yoshihiko Kondo
The bound kaon approach to the strangeness in the Skyrme model is applied to investigating the possibility of deeply bound states. We describe the system as two-Sky…
Bound kaon approach for the ppK- system in the Skyrme model
Tetsuo Nishikawa, Yoshihiko Kondo
The bound kaon approach to the strangeness in the Skyrme model is applied to exploring the possibility of deeply bound states. We derive the equation of motion for the kaon…
Positive and negative-parity flavor-octet baryons in coupled QCD sum rules
Yoshihiko Kondo, Osamu Morimatsu, Tetsuo Nishikawa +1
We apply the method of the QCD sum rule, in which positive- and negative-parity baryons couple with each other, to the flavor-octet hyperons and investigate the parity splittings.…
Coupled QCD sum rules for positive and negative-parity nucleons
Yoshihiko Kondo, Osamu Morimatsu, Tetsuo Nishikawa
A new approach of the QCD sum rule is proposed in which positive and negative-parity baryons couple with each other. With positive and negative-parity states explicitly taken into…
Theta++ from QCD sum rule
Tetsuo Nishikawa, Yoshiko Kanada-En'yo, Osamu Morimatsu +1
We study the pentaquark with and I=1 () in the QCD sum rule approach. We derive the QCD sum rules for positive and negative parity states of the pentaq…
Spin-3/2 pentaquark in the QCD sum rule
Tetsuo Nishikawa, Yoshiko Kanada-En'yo, Yoshihiko Kondo +1
We study and pentaquark states with in the QCD sum rule approach. The QCD sum rule for positive parity states and that for negative parity are…
