Strangeness neutrality and QCD thermodynamics [PDF]
SciPost Physics Core, 2020 Since the incident nuclei in heavy-ion collisions do not carry strangeness, the global net strangeness of the detected hadrons has to vanish. We investigate the impact of strangeness neutrality on the phase structure and thermodynamics of QCD at ...

Theoretical perspective on strangeness production
EPJ Web of Conferences, 2018 A brief review of some highlights and puzzles on strangeness production in heavy ion collisions is given. These include strangeness production and the nuclear equation of state; deeply subthreshold strangeness production; mean-field potentials on strange

Roles of Polyakov loops in Yang-Mills theory on 𝕋2 × ℝ2 [PDF]
EPJ Web of Conferences, 2022 We present an effective model of SU(N) pure Yang-Mills theory on 𝕋2 × ℝ2, where two directions are compactified with periodic boundary conditions. Our model includes two Polyakov loops serving as the order parameters of two center symmetries.

Equation of state and speed of sound of ( 2+1 )-flavor QCD in strangeness-neutral matter at nonvanishing net baryon-number density [PDF]
Physical Review D, 2022 We update results on the QCD equation of state in (2+1)-flavor QCD with non-zero conserved charge chemical potentials obtained from an eighth-order Taylor series.

What can we learn from the electromagnetic properties of hidden-charm molecular pentaquarks with single strangeness? [PDF]
Physical Review D, 2022 Inspired by the observation of the $P_{cs}(4459)$ and $P_{\psi s}^{\Lambda}(4338)$, we systematically investigate the magnetic moments, the transition magnetic moments, and the radiative decay behaviors of the $S$-wave isoscalar $\Xi_c^{(\prime)}\bar D^{(

Resummed lattice QCD equation of state at finite baryon density: Strangeness neutrality and beyond [PDF]
Physical Review D, 2022 We calculate a resummed equation of state with lattice QCD simulations at imaginary chemical potentials. This work presents a generalization of the scheme introduced in 2102.06660 to the case of non-zero $\mu_S$, focusing on the line of strangeness ...

Fluctuations and correlations of net baryon number, electric charge and strangeness in a background magnetic field [PDF]
European Physical Journal A, 2021 We present results on the second-order fluctuations of and correlations among net baryon number, electric charge and strangeness in (2 + 1)-flavor lattice QCD in the presence of a background magnetic field.

Analysis of the hidden-charm pentaquark molecular states with strangeness and without strangeness via the QCD sum rules [PDF]
Chinese Physics C, High Energy Physics & Nuclear Physics, 2021 In this article, we investigate the D̄Σc, D̄Ξ ′ c, D̄Σ ∗ c , D̄Ξ ∗ c , D̄ ∗Σc, D̄ ∗Ξ′c, D̄ ∗Σ∗c and D̄ ∗Ξ∗c pentaquark molecular states with strangeness and without strangeness via the QCD sum rules at length, pay much attention to the light flavor SU(3)

Strangeness content of the pion in the U(3) Nambu-Jona-Lasinio model [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2021 The Nambu-Jona-Lasinio model is considered with flavor-dependent coupling constants $G_{ij} \left[ ( \bar{\psi} \lambda_i \psi ) ( \bar{\psi} \lambda_j \psi ) + ( \bar{\psi} i\gamma_5 \lambda_i \psi ) ( \bar{\psi} i \gamma_5\lambda_j \psi ) \right ...
