Exotic Quark Structure of Lambda(1405) in QCD Sum Rule
T. Nakamura, J. Sugiyama, N. Ishii +2
A new analysis is performed in QCD sum rule for the lightest negative parity baryon Lambda (1405). Mixings of three-quark and five-quark Fock components are taken into account. Ter…
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…
Mixings of 4-quark components in light non-singlet scalar mesons in QCD sum rules
J. Sugiyama, T. Nakamura, N. Ishii +2
Mixings of 4-quark components in the non-singlet scalar mesons are studied in the QCD sum rules. We propose a formulation to evaluate the cross correlators of q\bar q and qq\bar q…
Effect of pion thermal width on the sigma spectrum
Tetsuo Nishikawa, Yoshimasa Hidaka, Munehisa Ohtani +1
We study the effect of the thermal width of on the spectral function of . In order to take into account a finite thermal width of , we replace the internal pion mass in t…
