Role of $f_{0} (980)$ and $a_{0} (980)$ in the $B^{-} \to π^{-} K^{+} K^{-}$ and $B^{-} \to π^{-} K^{0} K ˉ^{0}$ reactions

Luciano M. Abreu, Natsumi Ikeno, Eulogio Oset

In this work we study the role of the $f_{0} (980)$ and $a_{0} (980)$ resonances in the low $K^{+} K^{-}$ and $K^{0} K ˉ^{0}$ invariant-mass region of the $B^{-} \to π^{-} K^{+} K^{-}$ and $…

Model independent analysis of femtoscopic correlation functions: An application to the $D_{s 0}^{*} (2317)$

Natsumi Ikeno, Genaro Toledo, Eulogio Oset

We face the inverse problem of obtaining the interaction between coupled channels from the correlation functions of these channels. We apply the method to the interaction of the $D…

Predictions of super-exotic heavy mesons from $K^{} B^{} B^{*}$ interactions

M. Bayar, N. Ikeno, L. Roca

We make a theoretical study of the three-body system composed of $K ˉ^{*} B ˉ^{*} B ˉ^{*}$ to look for possible bound states, which could be associated to mesonic resonances…

Molecular states of $D^{} D^{} K ˉ^{*}$ nature

N. Ikeno, M. Bayar, E. Oset

We study the interaction of two $D^{*}$ and a $K ˉ^{*}$ by using the Fixed Center Approximation to the Faddeev equations to search for bound states of the three body system. Si…

Interpretation of the $Ω_{c} \to π^{+} Ω (2012) \to π^{+} (K ˉ Ξ)$ relative to $Ω_{c} \to π^{+} K ˉ Ξ$ from the $Ω (2012)$ molecular perspective

Natsumi Ikeno, Wei-Hong Liang, Genaro Toledo +1

We present a mechanism for $Ω_{c} \to π^{+} Ω (2012)$ production through an external emission Cabibbo favored weak decay mode, where the $Ω (2012)$ is dynamically generated from the inte…

$Z_{cs}$ states from the $D_{s}^{} D ˉ^{}$ and $J / ψ K^{*}$ coupled channels: Signal in $B^{+} \to J / ψ ϕ K^{+}$ decay

Natsumi Ikeno, Raquel Molina, Eulogio Oset

We study the $D_{s}^{*} D ˉ^{*}$ system in connection with the $J / ψ K^{*}$ in coupled channels and observe that, within reasonable values of the cut-off used to regularize the loops, t…

Combined theoretical study of the $D^{+} \to π^{+} η η$ and $D^{+} \to π^{+} π^{0} η$ reactions

Natsumi Ikeno, Melahat Bayar, Eulogio Oset

We study the $D^{+} \to π^{+} η η$ and $D^{+} \to π^{+} π^{0} η$ reactions, which are single Cabibbo suppressed and can proceed both through internal and external emission. The primary mechan…

Theoretical study of the $D^{0} \to K^{-} π^{+} η$ reaction

Genaro Toledo, Natsumi Ikeno, Eulogio Oset

We develop a model to study the $D^{0} \to K^{-} π^{+} η$ weak decay, starting with the color favored external emission and Cabibbo favored mode at the quark level. A less favored intern…

Molecular picture for the $Ω (2012)$ revisited

Natsumi Ikeno, Genaro Toledo, Eulogio Oset

We conduct a study of the interaction of the $K ˉ Ξ^{*}$ , $η Ω$ ( $s$ -wave) and $K ˉ Ξ$ ( $d$ -wave) channels within a coupled channel unitary approach where the transition potential…
