Meson Screening Masses in Thermal QCD

EPJ Web of Conferences, 2012
The quark-gluon plasma (QGP) excitations, corresponding to the scalar and pseudoscalar meson quantum numbers, for different temperatures are calculated.

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 $

Decays of mesons with charm quarks on the lattice [PDF]

, 2007
We investigate mesons containing charm quarks on fine lattices with a^{-1} \sim 5 GeV. The quenched approximation is employed using the Wilson gauge action at \beta = 6.6 and nonperturbatively O(a) improved Wilson quarks.

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.

Schwinger terms and pseudoscalar mesons

Nuclear Physics B, 1971
Effective meson operators are exhibited for a class of chiral SU(2) current models, and the general (12N, 12N) symmetry breaking Hamiltonian is constructed from Schwinger terms. A closed form is thus found for the corresponding non-linear pion Lagrangian in general coordinates.

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 ...

2+1 flavor domain wall QCD on a (2 fm)^3 lattice: light meson spectroscopy with Ls = 16

, 2007
We present results for light meson masses and pseudoscalar decay constants from the first of a series of lattice calculations with 2+1 dynamical flavors of domain wall fermions and the Iwasaki gauge action.
