Short-range baryon-baryon potentials in constituent quark model revisited

Takayasu Sekihara, Taishi Hashiguchi

We revisit the short-range baryon-baryon potentials in the flavor SU(3) sector, using the constituent quark model. We employ the color Coulomb, linear confining, and color magnetic…

Two-body wave functions and compositeness from scattering amplitudes: II. Application to the physical $N^{}$ and $Δ^{}$ resonances

Takayasu Sekihara

The meson-baryon molecular components for the $N^{*}$ and $Δ^{*}$ resonances are investigated in terms of the compositeness, which is defined as the norm of the two-body wave…

Further Theoretical Analysis on the $K^{-}^{3} He \to Λ p n$ Reaction for the $K ˉ N N$ Bound-State Search in the J-PARC E15 Experiment

Takayasu Sekihara, Eulogio Oset, Angels Ramos

Based on the scenario that a $K ˉ N N$ bound state is generated and it eventually decays into $Λ p$ , we calculate the cross section of the $K^{-}^{3} He \to Λ p n$ reac…

$K ˉ D ˉ N$ molecular state as a " $uu d s c ˉ$ pentaquark" in a three-body calculation

Junko Yamagata-Sekihara, Takayasu Sekihara

We predict a new three-body hadronic molecule composed of antikaon $K ˉ$ , anticharm meson $D ˉ$ , and nucleon $N$ with spin/parity $J^{P} = 1/ 2^{+}$ and isospin $I = 1/2$ . T…

Theoretical analysis on the $K^{-}^{3} He \to Λ p n$ reaction for the $K ˉ N N$ bound-state search in the J-PARC E15 experiment

Takayasu Sekihara, Eulogio Oset, Angels Ramos

We theoretically analyze the $K^{-}^{3} He \to Λ p n$ reaction for the $K ˉ N N$ bound-state search in the J-PARC E15 experiment. We find that, by detecting a fast and…

Possible $η^{'} d$ bound state and its $s$ -channel formation in the $γ d \to η d$ reaction

Takayasu Sekihara, Hiroyuki Fujioka, Takatsugu Ishikawa

We theoretically investigate a possibility of an $η^{'} d$ bound state and its formation in the $γ d \to η d$ reaction. First, in the fixed center approximation to the Faddeev e…
