Hadronic Molecules and the f0(980)/a0(980)

, 2008
We discuss a possible interpretation of the f0(980) and a0(980) mesons as hadronic molecules - bound states of K and Kbar mesons. Using a phenomenological Lagrangian approach we calculate the strong f0(980) to pi pi and a0(980) to pi eta as well as the ...

a0(980)−f0(980) mixing in χc1→π0f0(980)→π0π+π− and χc1→π0a0(980)→π0π0η

Physics Letters B, 2017
We study the isospin breaking in the reactions χc1→π0π+π− and χc1→π0π0η and its relation to the a0(980)−f0(980) mixing, which was measured by the BESIII Collaboration.

Flatte-like distributions and the a_0(980)/f_0(980) mesons [PDF]

The European Physical Journal A, 2004
We explore the features of Flatte-like parametrizations. In particular, we demonstrate that the large variation in the absolute values of the coupling constants to the pi-eta (or pi-pi) and KKbar channels for the a_0(980) and f_0(980) mesons that one can

Triangle singularity in the $$J/\psi \rightarrow K^+ K^- f_0(980)(a_0(980))$$ J/ψ→K+K-f0(980)(a0(980)) decays

European Physical Journal C: Particles and Fields, 2019
We study the $$J/\psi \rightarrow K^+ K^- f_0(980)(a_0(980))$$ J/ψ→K+K-f0(980)(a0(980)) reaction and find that the mechanism to produce this decay develops a triangle singularity around $$M_{\mathrm{inv}}(K^- f_0/K^- a_0) \approx 1515$$ Minv(K-f0/K-a0 ...

Cabibbo-favored Λc+→Λa0(980)+ decay in the final state interaction

Physics Letters B, 2021
The anti-triplet charmed baryon decays with the light scalar mesons are rarely measured, whereas the recent observation of the Cabibbo-favored Λc+→Ληπ+ decay hints a possible Λc+→Λa0(980)+,a0(980)+→ηπ+ process.

Isospin breaking and $f_0(980)$-$a_0(980)$ mixing in the $\eta(1405) \to \pi^{0} f_0(980)$ reaction [PDF]

, 2012
We make a theoretical study of the $\eta(1405) \to \pi^{0} f_0(980)$ and $\eta(1405) \to \pi^{0} a_0(980)$ reactions with an aim to determine the isospin violation and the mixing of the $f_0(980)$ and $a_0(980)$ resonances.
