and parameters of radial Regge trajectories within the bottom-up holographic
models for QCD is scrutinized. We show that the lattice data on the deconfine-
ment temperature can yield a powerful restriction on the spectrum of excited
mesons and glueballs within the framework of holographic approach. -

We extended our calculations of the recent research work for two flavor magnetized PNJL model cooperating non zero chemical potential and thermal mass in the potential as in the Lagrangian. We calculate the equation of state of PNJL model and its thermodynamic properties. We Show the results of the phase transition temperature obtain to a lower value in comparison to earlier value of phase...

At present, experiments devoted to studying collisions of hadrons and nuclei at high energy are being performed at various facilities, including the LHC and SPS (CERN) and RHIC (BNL). Due to the peculiarities of the strong interaction, constructing a collision model from the first principles of the QCD theory is a rather difficult task. Therefore, various empirical models are developed based...

The hadronization of the deconfinement matter is considered based on the concept the quark-hadron duality. Under such an approach the hadron rate is shown to be the convolutions of the multiple particle Green's function of quarks in the Kadanoff-Baym-Keldysh formalism with the probability to create the quasi-hadron bound quark-antiquarks states in the deconfinement matter. This probability...

The scalar quark condensate $\kappa(\rho)=\langle M|\sum_{i}\bar q_i q_i|M\rangle$ in nuclear matter can be presented as $\kappa(\rho) =\kappa(0) + \kappa_N\rho+S(\rho)$ with $\langle M|$ the ground state of the matter while $q$ are the operators of the light quarks $u$ and $d$. Here $\rho$ is the density of the matters, $\kappa(0)$ is the vacuum value of the condensate. In the second term on...

In many cases, interactions of nuclei are considered as collisions of A1 and A2 nucleons if it is possible to neglect the binding energy of the nucleus. However for very high kinetic energy of colliding nuclei there is a possibility of collective interaction of nucleons with production of quark-gluon matter blobs. As it was shown earlier, in this case a large orbital momentum appears. In that...

The theoretical consideration of the $NN{\bar K}$ quasi-bound system is based on the isotopic-spin formalism in which mesons ${\bar K}^0$ and $K^-$ are two isospin states of the $\bar K$ particle with the isospin of $\frac12$. Nucleon is also considered as isospin $\frac12$ particle having two states (proton and neutron) with the different projections of the isospin. According to the...

The spectroscopy of charmonium-like mesons with masses above the 2_mD open charm threshold has been full of surprises and remains poorly understood [1]. The currently most compelling theoretical descriptions of the mysterious XYZ mesons attribute them to hybrid structure with a tightly bound cc\bar diquark [2] or cq(cq)\bar tetraquark core [3 - 5] that strongly couples to S-wave DD\bar...
