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 ...

Strangeness neutrality and baryon-strangeness correlations [PDF]
Physical Review D, 2018 We derive a simple relation between strangeness neutrality and baryon-strangeness correlations. In heavy-ion collisions, the former is a consequence of quark number conservation of the strong interactions while the latter are sensitive probes of the ...

Strangeness in the Nucleon [PDF]
AIPConf.Proc.939:3-6,2007, 2007 There are several different experimental indications, such as the strangeness contribution to the magnetic moment of the proton, sigma_{\pi N} term, strange spin polarization, ratio of strange and non strange quark flavor distributions which suggest that the nucleon contains a hidden strangeness component which is contradictory to the naive constituent

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.

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^{(

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.

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 ...

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)
