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.

The (980) and (980) in the Process

Physics Letters, 2021
In this work, we have investigated the process Ds+→K+K−π+, taking into account the contributions from the S-wave pseudoscalar-pseudoscalar interaction within the chiral unitary approach, and also the intermediate ϕ resonance. By analyzing the BESIII and BABAR measurements, we conclude that the f0(980) state, dynamically generated from the S-wave ...

On nature of scalar a0(980) and f0(980)-mesons [PDF]

Nuclear Physics A, 2000
It is presented a critical consideration of all unusual properties of the scalar a_0(980) and f_0(980)-mesons in the four-quark, two-quark and molecular models. The arguments are adduced that the four-quark model is more preferable. It is discussed the complex of experiments that could finally resolve this issue.

Study a0(980)-f0(980) mixing from a0(980) -> f0(980) transition

, 2008
Various processes have been proposed previously to study a0(980)-f0(980) mixing through f0(980)->a0(980) transition. Here we investigate in detail the difference between a0(980)->f0(980) and f0(980)->a0(980) transitions. It is found that the a0(980)->f0(980) transition can provide additional constrains to the parameters of a0(980) and f0 ...

Study the CP violation of the quasi-two-body decays of B meson with the a00(980) and f0(980) mixing

Nuclear Physics B, 2023
In the framework of the QCD factorization approach, we study the localized CP violations of the B−→K−π+π−, B−→π−π+π−, B−→K−K+K−, B−→π−K+K−, B−→K−π0η and B−→π−π0η decays with and without the a00(980)−f0(980) mixing mechanism, respectively, and find that ...

Decays of sigma, kappa, a0(980) and fo(980) [PDF]

The European Physical Journal C, 2006
Ratios of coupling constants for these decays are compared with q-qbar predictions and Jaffe's 4-quark model. In both models, the predicted ratio g^2(kappa -> K-pi)/ g^2(sigma -> pi-pi) is much too small. Also, for q-qbar, the predicted ratio g^2(kappa -> K-eta ')/g^2(kappa -> K-pi) is much larger than observed. Both models fail for g^2(fo -
