The decay $η_{c} \to p p ˉ η$ with meson--baryon final-state interactions

Jing Song, Yu-Shan Ren, Eulogio Oset

We study the decay $η_c\to p\bar{p}η$ by combining the SU(3) flavor structure of the primary production with final-state interactions in the $pη$ and $\bar{p}η$ subsystems, u…

$K ˉ^{0} d$ Bound State and Correlation Function

M. Bayar, P. Encarnación, A. Feijoo +1

We study the $K ˉ^{0} d$ system using a new formulation of the fixed-center approximation that preserves elastic unitarity. The resulting scattering amplitude predicts a bound sta…

Line shapes of $Ω (2012)$ production in the $Ξ K ˉ$ and $Ξ π K ˉ$ decay channels

Natsumi Ikeno, Eulogio Oset

We theoretically study the line shape of the experiment for $Ω (2012)$ production in the $Ξ^{-} π^{+} K^{-}$ and $Ξ^{0} K^{-}$ decay modes, reflecting the $Ξ^{*} K ˉ$ and $Ξ K ˉ$ decay mod…

Theoretical description of the $D^{+} \to K ˉ^{0} π^{+} π^{0} π^{0}$ reaction

Zi-Ying Yang, Wen-Hao Jia, Dao-Chong Lin +5

We study the $D^{+} \to K ˉ^{0} π^{+} π^{0} π^{0}$ reaction, which shows two clear structures: the $K ˉ^{* 0}$ and $ρ^{+}$ in the $K ˉ^{0} π^{0}$ and $π^{+} π^{0…

Exotic states with charm and/or strangeness

A. Martínez Torres, Breno Agatão, Pedro Brandão +3

In this talk, I will discuss the properties of several exotic states with charm and/or strangeness. These states can be interpreted either as being generated from two- or three-had…

$K X (3872)$ interaction and correlation function

Jing Song, Pedro Brandao, Eulogio Oset

We investigate the $K X (3872)$ interaction and the corresponding correlation function, assuming the $X (3872)$ to be a molecular state of $D D ˉ^{*}$ and $D^{*} D ˉ$ with isospin…
