QCD Sum Rules and 1/ expansion: On the low energy dominance and separation of scattering backgrounds
Toru Kojo, Daisuke Jido
In multiquark correlator analyses with 1/Nc classifications, it is possible to separate the scattering background and to justify the factorization of condensates, which allows us t…
Dynamical study of bare pole with classifications
Toru Kojo, Daisuke Jido
Systematic counting of correlators is performed to directly relate quark-gluon dynamics to qualitatively different hadronic states order by order. Both 2q and 4q correlator…
Scalar Nonets in Pole-Dominated QCD Sum Rules
Toru Kojo, Daisuke Jido
The light scalar nonets are studied using the QCD sum rules for the tetraquark operators. The operator product expansion for the correlators is calculated up to dimension 12 and th…
Exotic Hadron in Pole-dominated QCD Sum Rules
Toru Kojo, Daisuke Jido, Arata Hayashigaki
We study pentaquark in the QCD sum rules emphasizing that we can not extract any properties of the pentaquark outside of the Borel window. To find the appropria…
Peristaltic modes of single vortex in the Abelian Higgs model
Toru Kojo, Hideo Suganuma, Kyosuke Tsumura
Using the Abelian Higgs model, we study the radial excitations of single vortex and their propagation modes along the vortex line. We call such beyond-stringy modes {\it peristalti…
