The electromagnetic form factors of light nuclei provide a sensitive test of our understanding of nuclei. The deuteron in particular, as the only bound two-nucleon system, is a fundamental system that has received extensive attention in the past, by both theory and experiment. Because the deuteron has spin one, three form factors are needed to fully describe the electromagnetic structure of...

The modeling of direct photons production in collisions of antiproton beam with the proton target "p pbar --> gamma + X" is done for the beam energy E_{beam} = 15 GeV using the simulation with PYTHIA6.4 generator and PandaRoot package.

Relativistic collisions of heavy ions produce a hot and dense matter similar to what existed in primordial Universe - the Quark-Gluon Plasma (QGP).
The hadronic collective flow was found to be one of the most pronounced signatures of the QGP.
Comparison of experimental data at RHIC energies with different hydrodynamical models revealed that the produced matter is not an ideal gas of quarks...

The charge distribution of nuclei is known with very high accuracy, i.e. in electron scattering experiments, conversely, the mass distribution is experimentally less accessible and therefore less precisely known. An accurate determination of the neutron density distribution is of particular interest. Especially in nuclei with N >> Z, a strong neutron skin is expected, since the excess...

Properties of Quark-Gluon Plasma (QGP) are being studied in ultrarelativistic heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC). One of the experimental probes that enable us to reveal the properties of the hot and dense strongly interacting medium are heavy quarks, such as $c$ and $b$. These quarks are created during the early stages of heavy-ion collisions and therefore...

The functional approach of Dyson-Schwinger and Bethe-Salpeter
Equations (DSE/BSE) allows us to investigate nonperturbative
properties of QCD.
We use this to study the Hadronic Vacuum Polarization contribution
to the anomalous magnetic moment of the muon, extending previous
calculations by including isospin symmetry breaking.

The log-lin dependence of the hadronic density of states with mass is known as the Hagedorn. A similar dependence is observed, at energies a factor of one thousand lower,in most atomic nuclei.
