Production of $B B ˉ$ bound state via $Υ (4 S)$ radiative decays

André L. M. Britto, Luciano M. Abreu

Motivated by recent theoretical predictions about the existence of a $B B ˉ$ bound state (also denoted as $X (10550)$ ), in this work we estimate the production of the $S$ -wav…

The $χ_{c 1} (4274)$ multiplicity in heavy-ion collisions

L. M. Abreu, A. L. M. Britto, F. S. Navarra +1

In a previous work we computed the thermally-averaged cross sections for the production and absorption of the $χ_{c 1} (4274)$ state in the hot hadron gas formed in heavy ion collisi…

$B^{+}$ 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…

Shedding light on the $X (3930)$ and $X (3960)$ states with the $B^{-} \to K^{-} J / ψ ω$ reaction

L. M. Abreu, M. Albaladejo, A. Feijoo +2

We have studied the contribution of the state $X (3930)$ , coming from the interaction of the $D D$ and $D_{s}^{+} D_{s}^{-}$ channels, to the $B^{-} \to K^{-} J / ψ ω$ decay. The pu…

$J / ψ$ decay to $ϕ, ω, K^{* 0}$ plus $f_{0} (1370)$ , $f_{0} (1710)$ , $K_{0}^{} (1430)$ , $f_{2} (1270)$ , $f_{2}^{'} (1525)$ and $K_{2}^{} (1430)$ : role of the $D$ -wave for tensor production

Luciano M. Abreu, Lianrong Dai, Eulogio Oset

We reassess the decay of the $J / ψ$ into an $ω, ϕ, K^{* 0}$ and one of the $f_{0} (1370)$ , $f_{0} (1710)$ , $f_{2} (1270)$ , $f_{2}^{'} (1525)$ , $K_{0}^{*} (1430)$ and $K_{2}^{*} (1430)$ resonances. We benefit…

The $D^{*} / D$ ratio in heavy ion collisions

L. M. Abreu, F. S. Navarra, H. P. L. Vieira

In this work we study the $D^{*}$ and $D$ multiplicities and how they change during the hadron gas phase of heavy ion collisions. With the help of an effective Lagrangian formalism,…
