Model analysis on the effectiveness of the HAL QCD method for hadron-hadron interactions
Takayasu Sekihara, Kei Fujiwara
The HAL QCD method has been one of the powerful tools to extract hadron-hadron interactions directly from lattice QCD simulation data. In this paper, we aim at examining the effect…
Feasibility study of the reaction for the "" pentaquark
Takayasu Sekihara, Hyun-Chul Kim, Atsushi Hosaka
We investigate theoretically the invariant mass spectrum of the reaction and scrutinize how the signal of the "" pentaquark, if it exists,…
interaction: meson exchanges, inelastic channels, and quasibound state
Takayasu Sekihara, Yuki Kamiya, Tetsuo Hyodo
Based on a baryon-baryon interaction model with meson exchanges, we investigate the origin of the strong attraction in the interaction, which was indicated by…
Two-body Wave Functions, Compositeness, And The Internal Structure Of Dynamically Generated Resonances
Takayasu Sekihara, Tetsuo Hyodo, Daisuke Jido +2
Recently, the compositeness, defined as the norm of a two-body wave function for bound and resonance states, has been investigated to discuss the internal structure of hadrons in t…
Exotic-Hadron Signature by Constituent-Counting Rule in Perturbative QCD
Wen-Chen Chang, H. Kawamura, S. Kumano +1
We explain a method to find internal quark configurations of exotic hadron candidates by using the constituent counting rule. The counting rule was theoretically predicted in pertu…
Dynamically Generated
Takayasu Sekihara
We show that the resonance can be dynamically generated in the -wave --- coupled-channels chiral unitary approach. In our model, the $Ξ(1…
