The principal element of a unified description of strongly interacting matter within effective theories is the hadronization of quarks at low temperatures and baryonic densities, while the partonic degrees of freedom are being suppressed in this regime. I present a novel approach to attack this problem, which is formulated based on a relativistic density-functional motivated by the string-flip...
The aim of the present report is to study nature of resonance state in $^6$Li within an extended three-cluster model. It is well-known that the nucleus $^6$Li has two sets of resonance states. The first set is formed by low-energy resonance states which lie close to the α+d decay threshold and are of positive parity. There are two very narrow and three broad resonance states in the first set....
Equation of state and electric (isospin) charge fluctuations are studied for matter composed of interacting pions. The pion matter is described by self interacting scalar fields via a $\phi^4-\phi^6$ type Lagrangian. The mean-field approximation is used and interaction parameters are fixed by fitting lattice QCD results on the isospin density as a function of the isospin chemical potential at...
We point out that the variance of net-baryon distribution normalized by the Skellam distribution baseline, $\kappa_2[B-\bar{B}]/B+\bar{B}$, is sensitive to the possible modification of (anti)baryon yields due to $B\bar{B}$ annihilation in the hadronic phase. The corresponding measurements can thus place stringent limits on the magnitude of the $B\bar{B}$ annihilation and its inverse reaction....
The Bose-Einstein condensation and the liquid-gas first-order phase transition are studied in the interacting pion matter. Two phenomenological models are used: the mean-field model and the hybrid model. Free model parameters are fixed by fitting the lattice QCD data on the pion Bose condensate density at zero temperature. In spite of some minor differences, the two models demonstrate an...
In [1] a simple method allowing one to estimate the times of maximal emission for pions and kaons,created in the LHC Pb+Pb collisions at $\sqrt{s_{NN}}=2.76$~TeV, based on the combined fitting of their $p_T$ spectra and the dependences of longitudinal femtoscopy radii on the pair transverse mass, $R_{\mathrm{long}}(m_T)$, was proposed and tested within the hydrokinetic model (HKM), able to...
Integrated hydro-kinetic model was modified and first time applied to baryon-rich matter created in heavy-ion collisions at relatively low energies of RHIC BES program. The model employs a transport approach at the early and late non-equilibrium stages of evolution of the system and viscous hydrodynamics with smooth continuous thermalization in the middle stage of near-equilibrium expansion of...
