B0 and Bs0 decays into J/ψ f0(980) and J/ψ f0(500) and the nature of the scalar resonances

Physics Letters B, 2014
We describe the B0 and Bs0 decays into J/ψ f0(500) and J/ψ f0(980) by taking into account the dominant process for the weak decay of B0 and Bs0 into J/ψ and a qq¯ component.

Branching fractions of semileptonic D and $$D_s$$ D s decays from the covariant light-front quark model

European Physical Journal C: Particles and Fields, 2017
Based on the predictions of the relevant form factors from the covariant light-front quark model, we show the branching fractions for the $$D (D_s) \rightarrow (P,\,S,\,V,\,A)\,\ell \nu _\ell $$ D ( D s ) → ( P , S , V , A ) ℓ ν ℓ ( $$\ell =e$$ ℓ = e or $

Pseudoscalar Mesons Scattering off D*-mesons with Chiral Perturbation Theory

EPJ Web of Conferences, 2012
We have systematically calculated the s-wave pseudoscalar mesons and D*- mesons scattering lengths to the third order with chiral perturbation theory, which will be helpful to reveal their strong interaction.

Scrutinizing Dark-Matter Scenarios with B → (K,$K^{\ast }$)$\overline{\mathit{\nu }}$ν Decays

Universe
Conceivable explanations of Belle-II measurements of a (surprising) excess of missing energy decays of the B meson to the K meson not covered by standard model neutrino–antineutrino pairs might be offered by additional contributions of dark matter ...

Chiral Symmetry restoration from the hadronic regime

EPJ Web of Conferences, 2017
We discuss recent advances on QCD chiral symmetry restoration at finite temperature, within the theoretical framework of Effective Theories. U(3) Ward Identities are derived between pseudoscalar susceptibilities and quark condensates, allowing to explain
