Correlation functions for $n D ˉ_{s 1} (2460)$ and $n D ˉ_{s 1} (2536)$

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

We study the interaction of the $n D ˉ_{s 1} (2460)$ and $n D ˉ_{s 1} (2536)$ systems from the perspective that the $D_{s 1} (2460)$ and $D_{s 1} (2536)$ states are molecular sta…

Fully-heavy tetraquarks in the vacuum and in a hot environment

Vinícius S. Silva, Cássio Pigozzo, Luciano M. Abreu

We study the thermal behavior of quarkonia and fully-heavy tetraquark states associated to the charmonium, bottomonium and bottom-charmonium mass spectra. The starting point is the…

A note on the tensor and vector exchange contributions to $K K ˉ \to K K ˉ, D D ˉ \to D D ˉ$ and $π^{+} π^{-} \to π^{+} π^{-}$ reactions

Luciano M. Abreu, Jing Song, Pedro C. S. Brandão +1

In this note we study the tensor and vector exchange contributions to the elastic reactions involving the pseudoscalars mesons $π^{+} π^{-}$ , $K^{+} K^{-}$ and $D^{+} D^{-}$ . In the case…

$B^{+}$ decay to $K^{+} η η$ with ( $η η$ ) from the $D D ˉ (3720)$ bound state

Pedro C. S. Brandão, Jing Song, Luciano M. Abreu +1

We search for a $B$ decay mode where one can find a peak for a $D D ˉ$ bound state predicted in effective theories and in Lattice QCD calculations, which has also been claimed…
