Two-particle correlations in azimuthal angle and pseudorapidity in central $^7$Be+$^9$Be collisions at the CERN Super Proton Synchrotron / Aduszkiewicz, A (NA61/SHINE Collaboration) /NA61
A measurement of charged hadron pair correlations in two-dimensional $\Delta\eta \Delta\phi$ space is presented. The analysis is based on total 30 million central Be+Be collisions observed in the NA61/SHINE detector at the CERN SPS for incident beam momenta of 19$A$, 30$A$, 40$A$, 75$A$, and 150$A$ GeV/$c$.

Measurements of $\Xi^-$ and $\overline{\Xi}^+$ production in proton-proton interactions at $\sqrt{s_{NN}}$ = 17.3 GeV in the NA61/SHINE experiment / Aduszkiewicz, A (NA61/SHINE Collaboration)
The production of $\Xi(1321)^{-}$ and $\overline{\Xi}(1321)^{+}$ hyperons in inelastic p+p interactions is studied in a fixed target experiment at a beam momentum of 158 GeV/$c$. Double differential distributions in rapidity and transverse momentum are obtained from a sample of 33M inelastic events. [...]

Search for an exotic S=-2, Q=-2 baryon resonance in proton-proton interactions at $\sqrt{s_{NN}}$ = 17.3~GeV / Aduszkieiwicz, A (NA61/SHINE Collaboration) /NA61
Pentaquark states have been extensively investigated theoretically in the context of the constituent quark model. In this paper experimental searches in the $\Xi^-$$\pi^-$, $\Xi^-$$\pi^+$, $\bar{\Xi}^+$$\pi^-$ and $\bar{\Xi}^+$$\pi^+$ invariant mass spectra in proton-proton interactions at $\sqrt{s}$=17.3~GeV are presented [...]

Measurements of hadron production in $\pi^{+}$ + C and $\pi^{+}$ + Be interactions at 60 GeV/$c$ / NA61/SHINE Collaboration
Precise knowledge of hadron production rates in the generation of neutrino beams is necessary for accelerator-based neutrino experiments to achieve their physics goals. NA61/SHINE, a large-acceptance hadron spectrometer, has recorded hadron+nucleus interactions relevant to ongoing and future long-baseline neutrino experiments at Fermi National Accelerator Laboratory. [...]

Measurements of production and inelastic cross sections for $\mbox{p}+\mbox{C}$, $\mbox{p}+\mbox{Be}$, and $\mbox{p}+\mbox{Al}$ at 60 GeV/$c$ and $\mbox{p}+\mbox{C}$ and $\mbox{p}+\mbox{Be}$ at 120 GeV/$c$ / NA61/SHINE Collaboration
This paper presents measurements of production cross sections and inelastic cross sections for the following reactions: 60~GeV/$c$ protons with C, Be, Al targets and 120~GeV/$c$ protons with C and Be targets. The analysis was performed using the NA61/SHINE spectrometer at the CERN SPS. [...]

Measurement of $\phi$ meson production in p+p interactions at 40, 80 and 158 GeV/$c$ with the NA61/SHINE spectrometer at the CERN SPS / Aduszkiewicz, A /NA61/SHINE Collaboration
Results on $\phi$ meson production in inelastic p+p collisions at CERN SPS energies are presented. They are derived from data collected by the NA61/SHINE fixed target experiment, by means of invariant mass spectra fits in the $\phi$ to $K^+ K^-$ decay channel. [...]

Proton-proton interactions and onset of deconfinement / Aduszkiewicz, A (NA61/SHINE Collaboration)
The NA61/SHINE experiment at the CERN SPS is performing a unique study of the phase diagram of strongly interacting matter by varying collision energy and nuclear mass number of colliding nuclei. In central Pb+Pb collisions the NA49 experiment found structures in the energy dependence of several observables in the CERN SPS energy range that had been predicted for the transition to a deconfined phase.

Measurements of $\pi^\pm$, $K^\pm$ and proton yields from the surface of the T2K replica target for incoming 31 GeV/$c$ protons with the NA61/SHINE spectrometer at the CERN SPS / NA61/SHINE Collaboration
Measurements of the $\pi^{\pm}$, $K^{\pm}$, and proton double differential yields emitted from the surface of the 90-cm-long carbon target (T2K replica) were performed for the incoming 31 GeV/c protons with the NA61/SHINE spectrometer at the CERN SPS using data collected during 2010 run. The double differential $\pi^{\pm}$ yields were measured with increased precision compared to the previously published NA61/SHINE results, while the $K^{\pm}$ and proton yields were obtained for the first time.
