 Measurement of the production cross section of 31 GeV/$c$ protons on carbon via beam attenuation in a 90-cm-long target / Acharya, A. (Jan Kochanowski U.) ; Adhikary, H. (Jan Kochanowski U.) ; Aduszkiewicz, A. (Warsaw U.) ; Allison, K.K. (Colorado U.) ; Andronov, E.V. (St. Petersburg State U.) ; Antićić, T. (Boskovic Inst., Zagreb) ; Babkin, V. (Dubna, JINR) ; Baszczyk, M. (AGH-UST, Cracow) ; Bhosale, S. (Cracow, INP) ; Blondel, A. (Paris U., VI-VII) et al. The production cross section of 30.92 GeV/$c$ protons on carbon is measured by the NA61/SHINE spectrometer at the CERN SPS by means of beam attenuation in a copy (replica) of the 90-cm-long target of the T2K neutrino oscillation experiment. The employed method for direct production cross-section estimation minimizes model corrections for elastic and quasi-elastic interactions.

 Measurements of $\pi^\pm$, $K^\pm$, $p$ and $\bar{p}$ spectra in $^7$Be+$^9$Be collisions at beam momenta from 19$A$ to 150$A$ GeV/$c$ with the NA61/SHINE spectrometer at the CERN SPS / Acharya, A (NA61/SHINE Collaboration) The NA61/SHINE experiment at the CERN Super Proton Synchrotron (SPS) studies the onset of deconfinement in hadron matter by a scan of particle production in collisions of nuclei with various sizes at a set of energies covering the SPS energy range. This paper presents results on inclusive double-differential spectra, transverse momentum and rapidity distributions and mean multiplicities of $\pi^\pm$, $K^\pm$, $p$ and $\bar{p}$ produced in the 20% most $central$ $^7$Be+$^9$Be collisions at beam momenta of 19$A$, 30$A$, 40$A$, 75$A$ and 150$A$ GeV/$c$.

 Measurements of $\pi^-$ production in $^7$Be+$^9$Be collisions at beam momenta from 19$A$ to 150$A$ GeV/$c$ in the NA61/SHINE experiment at the CERN SPS / Acharya, A (NA61/SHINE Collaboration) The NA61/SHINE collaboration studies at the CERN Super Proton Synchrotron (SPS) the onset of deconfinement in hadronic matter by the measurement of particle production in collisions of nuclei with various sizes at a set of energies covering the SPS energy range. This paper presents results on inclusive double-differential spectra and mean multiplicities of $\pi^{-}$ mesons produced in the 5% most $central$ $^7$Be+$^9$Be collisions at beam momenta of 19$A$, 30$A$, 40$A$, 75$A$ and 150$A$ GeV/$c$ obtained by the so-called $h^-$ method which does not require any particle identification.

 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. [...] CERN-EP-2020-102.- Geneva : CERN, 2020 - 21.

 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.
