A survey of dark matter and related topics in cosmology
This article presents an extensive review of the status of the search of the dark matter. The first eight sections are devoted to topics in dark...

Understanding light scalar meson by color-magnetic wave function in QCD sum rule
In this paper, we study the 0 + nonet mesons as tetraquark states with interpolating currents inspired by the color-magnetic wave function. This wave...

Δ -resonances: Quark models, chiral symmetry and AdS/QCD
The mass spectrum of Δ -resonances is compared to predictions based on three quark-model variants, to predictions assuming that chiral symmetry is...

Excited heavy tetraquarks with hidden charm
The masses of the excited heavy tetraquarks with hidden charm are calculated within the relativistic diquark–antidiquark picture. The dynamics of the...

Quark mass and the masses of Goldstone bosons
Based on the Dyson-Schwinger Equations (DSEs) of QCD in the “rainbow” approximation, the fully dressed quark propagator S f ( p ) is investigated, and...

Chiral corrections to the Roper mass
The quark mass dependence of the Roper mass is analyzed to one-loop order in covariant baryon chiral perturbation theory. The loop integrals are...

Relativistic three-quark equations and mass spectrum of the (70, 1−) baryon multiplet
A relativistic generalization of three-quark Faddeev equations for the particles of the (70, 1 − ) multiplet is constructed within the...

Constraints on nuclear-matter properties from QCD susceptibilities
In the framework of chiral theories, we establish the interrelation between the responses of the nuclear medium to probes which couple either to the...

Hadron spectrum and hadrons in the nuclear medium
Some recent developments in chiral dynamics of hadrons and hadrons in a medium are presented. Unitary schemes based on chiral Lagrangians describe...

Mesons in gauge/gravity duals
We review recent progress in studying mesons within gauge/gravity duality, in the context of adding flavour degrees of freedom to generalizations of...

Static properties and semileptonic decays of doubly heavy baryons in a nonrelativistic quark model
We evaluate static properties and semileptonic decays for the ground state of doubly heavy Ξ , Ξ ', Ξ * and Ω , Ω ', Ω * baryons. Working in the...

Coulomb gauge approach to qq̄g hybrid mesons
An effective Coulomb gauge Hamiltonian, H eff , is used to calculate the light (uūg), strange (ss̄g) and charmed (cc̄g) hybrid meson spectra. For the...

Chromomagnetism, flavour symmetry breaking and S-wave tetraquarks
The chromomagnetic interaction, with full account for flavour-symmetry breaking, is applied to S-wave configurations containing two quarks and two...

Structure and reactions of pentaquark baryons
We review the current status of the exotic pentaquark baryons. After a brief look at experiments of both positive and negative results, we discuss...
