Revising the $f_{1} (1420)$ resonance

V. R. Debastiani, F. Aceti, Wei-Hong Liang +1

We have studied the production and decay of the $f_{1} (1285)$ into $π a_{0} (980)$ and $K^{*} K ˉ$ as a function of the mass of the resonance and find a shoulder around 1400 MeV, tied t…

A Discussion on Triangle Singularities in the $Λ_{b} \to J / ψ K^{-} p$ Reaction

Melahat Bayar, Francesca Aceti, Feng-Kun Guo +1

We have analyzed the singularities of a triangle loop integral in detail and derived a formula for an easy evaluation of the triangle singularity on the physical boundary. It is ap…

The " $a_{1} (1420)$ " peak as the $π f_{0} (980)$ decay mode of the $a_{1} (1260)$

F. Aceti, L. R. Dai, E. Oset

We study the decay mode of the $a_{1} (1260)$ into a $π^{+}$ in p-wave and the $f_{0} (980)$ that decays into $π^{+} π^{-}$ in s-wave. The mechanisms proceeds via a triangular mechanism where…

The $K K ˉ π$ decay of the $f_{1} (1285)$ and its nature as a $K^{*} K ˉ - cc$ molecule

F. Aceti, Ju-Jun Xie, E. Oset

We investigate the decay of $f_{1} (1285) \to π K K ˉ$ with the assumption that the $f_{1} (1285)$ is dynamically generated from the $K^{*} K ˉ - cc$ interaction. In addition to the…

$f_{1} (1285)$ decays into $a_{0} (980) π^{0}$ , $f_{0} (980) π^{0}$ and isospin breaking

F. Aceti, J. M. Dias, E. Oset

We evaluate the decay width for the processes $f_{1} (1285) \to π^{0} a_{0} (980)$ and $f_{1} (1285) \to π^{0} f_{0} (980)$ taking into account that all three resonances are dynamically generated…

Study of $B B ˉ^{}$ and $B^{} B ˉ^{*}$ interactions in $I = 1$ and relationship to the $Z_{b} (10610)$ , $Z_{b} (10650)$ states

J. M. Dias, F. Aceti, E. Oset

We use the local hidden gauge approach in order to study the $B B ˉ^{*}$ and $B^{*} B ˉ^{*}$ interactions for isospin I=1. We show that both interactions via one light meson exchan…

Signature of an $h_{1}$ state from $J / ψ \to η K^{* 0} K ˉ^{* 0}$ and theoretical description of the $Z_{c} (3900)$ and $Z_{c} (4020)$ as $D D ˉ^{}$ and $D^{} D ˉ^{*}$ molecular states

E. Oset, J. J. Xie, M. Albaladejo +11

In this talk we address two topics: The first one is an empirical explanation in terms of a new state $h_{1}$ of the peak in the $K^{* 0} K ˉ^{* 0}$ invariant mass distribution clos…

The composite nature of the $Λ (1520)$ resonance

F. Aceti, E. Oset, L. Roca

Recently, the Weinberg compositeness condition of a bound state was generalized to account for resonant states and higher partial waves. We apply this extension to the case of the…

Prediction of an $I = 1$ $D D ˉ^{*}$ state and relationship to the claimed $Z_{c} (3900)$ , $Z_{c} (3885)$

F. Aceti, M. Bayar, E. Oset +5

We study here the interaction of $D D ˉ^{*}$ in the isospin $I = 1$ channel in the light of recent theoretical advances that allow to combine elements of the local hidden gauge appr…

Prediction of a $Z_{c} (4000)$ $D^{} D ˉ^{}$ state and relationship to the claimed $Z_{c} (4025)$

F. Aceti, M. Bayar, J. M. Dias +1

After discussing the OZI suppression of one light meson exchange in the interaction of $D^{*} D ˉ^{*}$ with isospin I=1, we study the contribution of two pion exchange to the intera…

Meson baryon components in the states of the baryon decuplet

F. Aceti, L. R. Dai, L. S. Geng +2

We apply an extension of the Weinberg compositeness condition on partial waves of $L = 1$ and resonant states to determine the weight of meson-baryon component in the $Δ (1232)$ reson…

The small $K π$ component in the $K^{*}$ wave functions

C. W. Xiao, F. Aceti, M. Bayar

We use a recently developed formalism which generalizes the Weinberg's compositeness condition to partial waves higher than s-wave in order to determine the probability of having a…

Isospin breaking and $f_{0} (980)$ - $a_{0} (980)$ mixing in the $η (1405) \to π^{0} f_{0} (980)$ reaction

F. Aceti, W. H. Liang, E. Oset +2

We make a theoretical study of the $η (1405) \to π^{0} f_{0} (980)$ and $η (1405) \to π^{0} a_{0} (980)$ reactions with an aim to determine the isospin violation and the mixing of the $f_0…

The $X (3872) \to J / ψ γ$ decay in the $D D ˉ^{*}$ molecular picture

F. Aceti, R. Molina, E. Oset

From a picture of the X(3872) where the resonance is a bound state of $D ˉ D^{*} - c . c .$ , we evaluate the decay width into the $J / ψ γ$ channel, which is sensitive to the internal str…

Wave functions of composite hadron states and relationship to couplings of scattering amplitudes for general partial waves

F. Aceti, E. Oset

In this paper we present the connection between scattering amplitudes in momentum space and wave functions in coordinate space, generalizing previous work done for s-waves to any p…
