Abstract In the present work, we investigate impact of finite volume on in-medium properties kaons (K+, K0), antikaons (K−, $\bar{K^0}$), and φ mesons in isospin asymmetric strange hadronic medium at density temperature. We use chiral SU(3) mean-field model, which accounts for interactions between baryons through exchange scalar (σ, ζ, δ) vector (ω, ρ, φ) fields. To effects volume, apply multiple reflection expansion (MRE) technique calculations states. At high baryon density, an increase...

In the current work, we present influence of finite volume and magnetic field on thermodynamic properties isospin asymmetric quark matter using Polyakov loop extended chiral SU(3) mean (PCQMF) model at chemical potential temperature. Within PCQMF model, use scalar vector values in mean-field approximation to obtain properties: pressure density, entropy energy density. The susceptibilities conserved charges for strongly interacting different system sizes as well have been studied. A sizable...

Abstract In this study, the susceptibilities of conserved charges, baryon number, charge and strangeness number at zero low values chemical potential are presented. Taylor series expansion was used to obtain results for three-flavor Polyakov quark meson (PQM) model loop extended chiral mean-field (PCQMF) model. Mean-field approximation study matter with inclusion isospin potential, as well vector interactions. The effects vector-interactions on phase diagrams were analyzed. A comparative...

In the present work, we investigate impact of finite volume on in-medium properties kaons ($K^+$, $K^0$) and antikaons ($K^-$, $\bar{K^0}$), $\phi$ mesons in isospin asymmetric strange hadronic medium at density temperature. We use chiral SU(3) mean-field model, which accounts for interactions between baryons through exchange scalar ($\sigma, \zeta, \delta $) vector ($\omega$, $\rho$, $\phi$) fields. To effects volume, apply multiple reflection expansion (MRE) technique calculations states....

This paper investigates the impact of strangeness chemical potential and finite volume on QCD critical end point by employing a (2+1) flavored Polyakov quark meson model. Within mean-field approximation, model has been extended to study effect vector interactions thermodynamics isospin-asymmetric matter. Susceptibilities conserved charges like number are analyzed using Taylor's series expansion. The chiral phase transition boundary in diagram is found be shifted towards higher values ($μ_q$)...
