A KKN system with I=1/2 and J{sup P}=1/2{sup +} is investigated with nonrelativistic three-body calculations by using effective KN and KK interactions. The present investigation suggests that a weakly bound state for the KKN system can be formed below the two-body threshold of K and quasibound KN with a 40{approx}60 MeV decay width of KKN{yields}{pi}YK. This corresponds to an excited {xi} baryon with J{sup P}=1/2{sup +} located around 1.9 GeV. Studying the wave function of the KKN system…

KK̄N and K̄K̄N Molecular States with I = 1/2, 3/2 and J P = 1/2 + Studied with Three-Body Faddeev Calculations
Using the Akaishi—Yannazaki (AY) and Hyodo—Weise (HW) effective K, N, and KN interactions, we study possible existence of KN and N molecule states with I = 1/2,3/2 and JP = 1/2+ by means of
K¯D¯N molecular state as a “ uudsc¯ pentaquark” in a three-body calculation
We predict a new three-body hadronic molecule composed of antikaon K¯, anticharm meson D¯, and nucleon N with spin-parity JP=1/2+ and isospin I=1/2. This state behaves like an explicit pentaquark
A new N* resonance as a hadronic molecular state
We report our recent work on a hadronic molecule state of the KN system with I = 1/2 and JP = 1/2+. We assume that the Λ(1405) resonance and the scalar mesons, f0 (980), a0 (980), are reproduced as
Three-body calculations for the K - pp system within potential models
We present three-body nonrelativistic calculations within the framework of a potential model for the kaonic cluster K − pp using two methods: the method of hyperspherical harmonics in the momentum
Baryon resonances as hadronic molecule states with kaons
We investigate hadronic molecule states of $K \bar K N$ and $\bar K \bar K N$ systems with I = 1/2 and JP = 1/2 + , assuming that Λ(1405) and the scalar mesons, f0(980), a0(980), are reproduced as
Few Body Systems Made of Pseudoscalars
Few body systems made of pseudoscalars, like $${K\, K \, \bar K,\,\pi \, K \, \bar K}$$ , are studied within a coupled channel approach based on solving the Faddeev equations considering two-body
Deeply quasi-bound state in single- and double-$\bar{K}$K¯ nuclear clusters
Abstract.New calculations of the quasi-bound state positions in $K^{-}K^{-}pp$K-K-pp kaonic nuclear cluster are performed using non-relativistic four-body Faddeev-type equations in AGS form. The
Formation spectra of light kaonic nuclei by in-flight (K̄,N) reactions with a chiral unitary amplitude
We study theoretically the in-flight (K{sup -},N) reactions for the formation of light kaonic nuclear systems to get deeper physical insights on the spectra and to investigate the formation spectra
On Mass Polarization Effect in Three-Body Nuclear Systems
The mass polarization effect is considered for different three-body nuclear AAB systems having a strongly bound AB and unbound AA subsystems. We employ the Faddeev equations for calculations and the
