RADIATIVE WEAK DECAYS OF CHARM MESONS
The standard model radiation conversion pseudo-scalar meson D radiation electromagnetic penguins amplitude and amplitude
2014/12/23
We address standard model predictions for flavor-changing radiative transitions of the pseudoscalar charm mesons. Short-distance contributions in D radiative transitions are contrasted with those in B...
Factorization in non-leptonic decays of heavy mesons
Model calculation the heavy meson decays pseudoscalar transformation
2014/12/22
We propose a QCD-based model for calculation of the non-perturbative corrections to the factorization approximation in the decays of heavy mesons. In the framework of the model, factorization in pseud...
Properties of quarks and mesons in the Dyson-Schwinger/Bethe-Salpeter approach
Dyson-Schwinger/Bethe-Salpeter mesons
2011/7/21
In this thesis, the Dyson-Schwinger - Bethe-Salpeter formalism is investigated and used to study the meson spectrum at zero temperature, as well as the chiral phase transition in finite-temperature QC...
Unitary coupled-channels model for three-mesons decays of heavy mesons
heavy-meson hadronic decay exotic meson 3-body unitarity
2011/7/21
A unitary coupled-channels model is presented for investigating the decays of heavy mesons and excited meson states into three light pseudoscalar mesons. The model accounts for the three-mesons final ...

2011/7/21
The scalar mesons $\sigma(600)$, $\kappa(800)$, $f_0(980)$ and $a_0(980)$ together with the pseudo Goldstone bosons $\pi$, $K$, and $\eta$ may be considered as the Higgs sector of strong interaction.
Chiral symmetry breaking and the spin content of the rho and rho' mesons
Chiral symmetry breaking rho rho' mesons
2011/7/21
Using interpolators with different SU(2)_L \times SU(2)_R transformation properties we study the chiral symmetry and spin contents of the rho- and rho'-mesons in lattice simulations with dynamical qua...
