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 ...
Study of $ππ$ correlations at LHC and RHIC energies in $pp$ collisions within the quark-gluon string model
quark-gluon string model RHIC energies
2011/7/21
The Quark Gluon String Model (QGSM) reproduces well the global characteristics of the $pp$ collisions at RHIC and LHC, e.g., the pseudorapidity and transverse momenta distributions at different centra...
A model for space and time-like proton (neutron) form factors
space time-like proton (neutron)
2011/7/21
Recent experiments on the electromagnetic proton and neutron form factors reveal very peculiar features such as the decreasing of the ratio of electric to magnetic form factor of the proton as functio...

We determine the value of the omega -rho- pi mesons coupling (g_{omega rho pi}), in the context of the vector meson dominance model, from radiative decays, the omega -> 3 pi decay width and the e^+e^-...
The thermal model on the verge of the ultimate test: particle production in Pb-Pb collisions at the LHC
ultimate test thermal model on the verge Pb-Pb collisions
2011/7/21
We investigate the production of hadrons in nuclear collisions within the framework of the thermal (or statistical hadronization) model. We discuss both the ligh-quark hadrons as well as charmonium an...
Alpha-Cluster Model, Charge Symmetry of Nuclear Force and Single Particle Bound State Potential in Symmetrical Nuclei
Alpha-Cluster Model Nuclear Force Bound State Potential
2011/7/20
A phenomenological alpha-cluster model based on the charge symmetry of nuclear force allows one to estimate the last proton position radius (LPPR) in a symmetrical nucleus. The values of LPPR obtained...
Rotational Bands and Electromagnetic Transitions of some even-even Neodymium Nuclei in J-Projected Hartree-Fock Model
J-Projected Hartree-Fock Model Nuclei Electromagnetic Transitions
2011/7/20
Rotational structures of even-even $^{148-160}$Nd nuclei are studied with the self-consistent deformed Hartree-Fock (HF) and angular momentum (J) projection model. Spectra of ground band, recently obs...
$η$ photoproduction on the quasi-free nucleons in the chiral quark model

Quark model study of multiquark states
quark model dibaryon tetraquark color confinement multibody interaction
2009/11/24
The six- and four-quark systems are studied in the framework of constituent quark models. It is emphasized that the color confinement used in multiquark system should be different from the one used in...
