Abstract.We propose to use the thermal model formulation that employs the multi-component hard-core radii to describe the hadron yield ratios from the low AGS to the highest RHIC energies. It is demonstrated that the variation of the hard-core radii of pions and kaons enable us to drastically improve the fit quality of the measured mid-rapidity data and for the first time to completely describe the Strangeness Horn behavior as the function of the energy of collision without spoiling the fit… 
Hard-Core Radius of Nucleons within the Induced Surface Tension Approach
We review the recent approach to model the hadronic and nuclear matter equations of state using the induced surface tension concept, which allows one to go far beyond the usual Van der Waals
Resolving the hyper-triton yield description puzzle in high energy nuclear collisions
The recently developed hadron resonance gas model with multicomponent hard-core repulsion is used to address and resolve the long standing problem to describe the light nuclear cluster multiplicities
Separate freeze-out of strange particles and the quark-hadron phase transition
The scenario of the independent chemical freeze-outs for strange and nonstrange particles is discussed. Within such a scenario an apparent in-equilibrium of strangeness is naturally explained by a
Surprisingly large uncertainties in temperature extraction from thermal fits to hadron yield data at LHC
The conventional hadron-resonance gas (HRG) model with the Particle Data Group (PDG) hadron input, full chemical equilibrium, and the hadron type dependent eigenvolume interactions is employed to fit
Non-smooth Chemical Freeze-out and Apparent Width of Wide Resonances and Quark Gluon Bags in a Thermal Environment
Here we develop the hadron resonance gas model with the Gaussian mass attenuation. This model allows us to treat the usual hadrons and the quark gluon bags on the same footing and to study the
A possible evidence of observation of two mixed phases in nuclear collisions
Using an advanced version of the hadron resonance gas model we have found several remarkable irregularities at chemical freeze-out. The most prominent of them are two sets of highly correlated
Hadron resonance gas model with induced surface tension
Abstract.Here we present a generalization of the multicomponent Van der Waals equation of state in the grand canonical ensemble. For the one-component case the third and fourth virial coefficients
Separate chemical freeze-outs of strange and non-strange hadrons and problem of residual chemical non-equilibrium of strangeness in relativistic heavy ion collisions
We present an elaborate version of the hadron resonance gas model with the combined treatment of separate chemical freeze-outs for strange and non-strange hadrons and with an additional $\gamma_{s}$
New signals of quark-gluon-hadron mixed phase formation
Abstract.Here we present several remarkable irregularities at chemical freeze-out which are found using an advanced version of the hadron resonance gas model. The most prominent of them are the sharp

Description of Hot and Dense Hadron Gas Properties in a New Excluded-Volume model
A new equation of state for a hot and dense hadron gas (HG) is obtained where the finite hard-core size of baryons has been incorporated in a thermodynamically consistent formulation of excluded
Quark gluon bags as reggeons
The influence of the medium-dependent finite width of quark gluon plasma (QGP) bags on their equation of state is analyzed within an exactly solvable model. It is argued that the large width of the
Chemical equilibrium study in nucleus-nucleus collisions at relativistic energies
We present a detailed study of chemical freeze-out in nucleus-nucleus collisions at beam energies of $11.6A$, $30A$, $40A$, $80A$, and $158A\phantom{\rule{0.3em}{0ex}}\text{GeV}$. By analyzing
Fresh look at the Hagedorn mass spectrum as seen in the experiments
The medium-dependent finite width is introduced into an exactly solvable model with the general mass-volume spectrum of the QGP bags. The model allows us to estimate the minimal value of the QGP
Strange and multi-strange particle ratios in p+p reactions at \sqrt{s} = 200 GeV at RHIC
Mid-rapidity anti-particle to particle ratios for strange and multi-strange baryons in inelastic p+p collisions at √s = 200 GeV have been determined using the STAR detector. The observed ratios are
Near-threshold production of the multistrange Xi- hyperon.
TLDR
In central collisions the Xi(-) yield is found to be in excellent agreement with statistical and transport model predictions, suggesting that multistrange hadron production approaches chemical equilibrium in high baryon density nuclear matter.
