Large isospin symmetry violation in kaon production? / Brylinski, Wojciech (Warsaw U. of Tech. (main)) /NA61/SHINE Collaboration
The recent measurements of kaon production in Ar+Sc collisions at 75A GeV/c (√SNN = 11.94 GeV) performed by NA61/SHINE at the CERN SPS resulted in determining the ratio of charged to neutral kaons to be 1.26 ± 0.06. The result, well above unity, cannot be explained by models accounting for known isospin symmetry violating processes. [...]

Femtoscopy using Lévy-distributed sources at NA61/SHINE / Porfy, Barnabas (Wigner RCP, Budapest) /NA61/SHINE Collaboration
In the recent years, research studies in high-energy physics have confirmed the creation of the strongly interacting quark-gluon plasma (sQGP) in ultra-relativistic nucleus-nucleus collisions. NA61/SHINE at CERN SPS investigates hadronic matter properties by varying collision energy ($\sqrt{s_{\rm{NN}}} \approx 5.3, 6.2, 7.7, 8.8, 12$, and 16.8 GeV) and systems (such as p+p, p+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb). [...]

Energy dependence of $\phi$(1020) meson production in nucleus-nucleus collisions at the CERN SPS / Rozpłochowski, Łukasz
This paper presents preliminary results from the NA61/SHINE experiment on $\phi$ meson production in central Ar+Sc collisions at beam momenta of 150$A$, 75$A$, and 40$A$ GeV/$c$ (corresponding to $\sqrt{s_{NN}}$ = 16.8, 11.9, and 8.8 GeV, respectively). [...]

$K^*/K$ ratio and the time between freeze-outs for intermediate-mass Ar+Sc system at the SPS energy range / Kozłowski, Bartosz /NA61/SHINE Collaboration
Resonance production is one of the key observables to study the dynamics of high-energy collisions. In dense systems created in heavy nucleus-nucleus collisions, the properties of some of them (widths, masses, branching ratios) were predicted to be modified due to partial restoration of chiral symmetry. [...]

$K_S^0$ production in p+p interactions measured by NA61/SHINE / Ćirković, Marjan (Belgrade U.) /NA61/SHINE Collaboration
The NA61/SHINE collaboration measured the production of $K_S^0$ in p+p interactions at two beam momenta: 80 and 158 GeV/c. The $\pi^+ + \pi^-$ decay of $K_S^0$(branching ratio of 69.2%) wasmeasured via the invariant mass method. [...]

Femtoscopy analysis in small systems at NA61/SHINE / Porfy, Barnabas (Eotvos U., Dept. Atomic Phys. ; Wigner RCP, Budapest) /NA61/SHINE Collaboration
Recent measurements of femtoscopic correlations at NA61/SHINE unravel that the shape of the particle emitting source is not Gaussian. The measurements are based on Lévy-stable symmetric sources, and we discuss the average pair transverse mass dependence of the source parameters. [...]
