Critical view of the claimed $Θ^{+}$ pentaquark

E. Oset, A. Martinez Torres

We use a theoretical model of the $γ d \to K^{+} K^{-} n p$ reaction adapted to the experiment done at LEPS where a peak was observed and associated to the $Θ^{+} (1540)$ pentaquark…

An alternative explanation for the $Θ (1540)$ pentaquark peak

A. Martínez Torres, E. Oset

We have studied the $γ d \to K^{+} K^{-} n p$ reaction in which the LEPS collaboration found a signal in the $K^{+} n$ invariant mass for the claimed $Θ (1540)$ pentaquark peak. Our study…

Limits to the Fixed Center Approximation to Faddeev equations: the case of the $ϕ (2170)$

A. Martínez Torres, E. J. Garzon, E. Oset +1

The Fixed Center Approximation to the Faddeev equations (FCA) has been used lately with success in the study of bound systems of three hadrons. It is also important to set the limi…

The $f_{0} (1370)$ , $f_{0} (1710)$ , $f_{2} (1270)$ , $f_{2}^{'} (1525)$ , and $K_{2}^{*} (1430)$ as dynamically generated states from vector meson - vector meson interaction

L. S. Geng, E. Oset, R. Molina +5

We report on some recent developments in understanding the nature of the low-lying mesonic resonances $f_{0} (1370)$ , $f_{0} (1710)$ , $f_{2} (1270)$ , $f_{2}^{'} (1525)$ , and $K_{2}^{*} (1430)$ . In par…

Three body systems with strangeness and exotic systems

E. Oset, A. Martinez Torres, K. P. Khemchandani +1

We report on four $Σ$ 's and three $Λ$ 's, in the 1500 - 1800 MeV region, as two meson - one baryon S-wave $(1/2)^{+}$ resonances found by solving the Faddeev equations in the coupled…

Faddeev fixed-center approximation to the $N K ˉ K$ system and the signature of a $N^{*} (1920) (1/ 2^{+})$ state

Ju-Jun Xie, A. Martínez Torres, E. Oset

We perform a calculation for the three body $N K ˉ K$ scattering amplitude by using the fixed center approximation to the Faddeev equations, taking the interaction between $N$ …
