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 the \phi(1020)f_0(980) S-wave scattering and the Y(2175) resonance
, 2009 We have studied the \phi(1020)f_0(980) S-wave scattering at energies around threshold employing chiral Lagrangians coupled to vector mesons through minimal coupling. The interaction kernel is obtained by considering the f_0(980) as a K\bar{K} bound state.

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 -

Isospin breaking and f0(980)-a0(980) mixing in the η(1405) → π0f0(980) reaction
EPJ Web of Conferences, 2014 We make a theoretical study of the η(1405) → π0f0(980) and η(1405) → π0a0(980) reactions to determine the isospin violation and the mixing of the f0(980) and a0(980) resonances. We make use of the chiral unitary approach where these two resonances appear

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma
Molecular Oncology, EarlyView.Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Study the $$B^{0}_{(s)}$$ B ( s ) 0 decays into $$\phi $$ ϕ and a scalar or vector meson
European Physical Journal C: Particles and Fields, 2021 In the present work, we investigate the decays of $$B^{0}_{(s)} \rightarrow \phi \pi ^{+}\pi ^{-}$$ B ( s ) 0 → ϕ π + π - with the final state interaction based on the chiral unitary approach. In the final state interaction of the $$\pi ^+\pi ^-$$ π + π -

Analysis the $f_0(980)$ and $a_0(980)$ mesons as four-quark states with the QCD sum rules
, 2005 In this article, we take the point of view that the scalar mesons $ f_0(980)$ and $a_0(980)$ are diquark-antidiquark states $(qq)_{\bar{3}}(\bar{q}\bar{q})_3$, and devote to determine their masses in the framework of the QCD sum rules approach with the ...
