Chemical freeze-outs of strange and non-strange particles and residual chemical non-equilibrium
K. A. Bugaev, D. R. Oliinychenko, V. V. Sagun +4
We propose 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 addit…
Non-smooth Chemical Freeze-out and Apparent Width of Wide Resonances and Quark Gluon Bags in a Thermal Environment
K. A. Bugaev, A. I. Ivanytskyi, D. R. Oliinychenko +3
Here we develop the hadron resonance gas model with the Gaussian width of hadron resonances. This model allows us to treat the usual hadrons and the quark gluon bags on the same fo…
Bimodality Phenomenon in Finite and Infinite Systems Within an Exactly Solvable Statistical Model
V. V. Sagun, A. I. Ivanytskyi, K. A. Bugaev +1
We present a few explicit counterexamples to the widely spread belief about an exclusive role of the bimodal nuclear fragment size distributions as the first order phase transition…
Chemical Freeze-out of Strange Particles and Possible Root of Strangeness Suppression
K. A. Bugaev, D. R. Oliinychenko, J. Cleymans +4
Two approaches to treat the chemical freeze-out of strange particles in hadron resonance gas model are analyzed. The first one employs their non-equillibration via the usual γ_s fa…
Is bimodality a sufficient condition for a first order phase transition existence?
K. A. Bugaev, A. I. Ivanytskyi, V. V. Sagun +1
Here we present two explicit counterexamples to the widely spread beliefs about an exclusive role of bimodality as the first order phase transition signal. On the basis of an exact…
The statistical multifragmentation model for liquid-gas phase transition with a compressible nuclear liquid
V. V. Sagun, A. I. Ivanytskyi, K. A. Bugaev +1
We propose a new formulation of the statistical multifragmentation model based on the analysis of the virial expansion for a system of the nuclear fragments of all sizes. The devel…
