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 ...

Structure of scalar mesons Higgs sector strong interaction
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...

2011/7/21
Invariant cross sections for neutral pions and eta mesons in pp collisions at sqrt(s) = 0.9, 2.76, and 7 TeV were measured by the ALICE detector at the Large Hadron Collider. Next-to-leading order (NL...

2011/1/4
We report the first measurement of the differential cross section on $\phi$-meson photoproduction from deuterium near the production threshold for a proton using the CLAS detector and a tagged-photon ...

2011/1/4
Photoproduction of \eta mesons off light nuclei (d, 3He, 7Li) has been measured at the tagged photon beam of the Mainz MAMI accelerator with the combined Crystal Ball/TAPS detection system. Special at...
Rare semileptonic decays of heavy mesons in the heavy quark limit
weak decay heavy quark flavor symmetry
2010/1/18
We study the branching ratios of D+→D0e+ν, D+S→D0e+ν, B0S→B+e－ν, D+S→D+ e－e+ and B0S→B0e－e+ rare semileptonic decay processes, which are induced by decays of light quarks, the heavy quarks remain unch...
Relativistic studies of the decay constants of S wave and P wave mesons
decay constant Bethe-Salpeter relativistic heavy meson
2010/1/18
Relativistic corrections are important in hadronic physics since even for the heavy hadrons there are sizable relativistic corrections. Therefore one should use a relativistic model to describe the hi...
Photoproduction of mesons off the deuteron: quasifree and coherent processes

Using a multisource ideal gas (MSIG) model, we reconstruct the transverse emission source in the momentum space for light fragments produced in reactions 86Kr-124Sn at 25 MeV/nucleon and b=7—10 fm bas...
I review some of the recent experimental results on the so-called XYZ mesons.
The Importance of Strange Mesons in Neutron Star Properties
Strange Mesons Neutron Star Properties
2010/10/15
In order to obtain the properties of compact stellar objects, appropriate equations of state have to be used. In the literature, strange meson fields, namely the scalar meson field s¤(975) and the vec...

Weak Decay Constant Pseudoscalar Mesons a QCD-Inspired Model
2010/10/19
We show that a linear scaling between the weak decay constants of pseudoscalars and the vector meson masses is supported by the available experimental data. The decay constants scale as fm=f¼ =...
