Measurements of inclusive spectra and mean multiplicities of $\pi^\pm$, K$^\pm$, p and $\bar{\textrm{p}}$ produced in inelastic p+p interactions at incident projectile momenta of 20, 31, 40, 80 and 158 GeV/c ($\sqrt{s} = $ 6.3, 7.7, 8.8, 12.3 and 17.3 GeV, respectively) were performed at the CERN Super Proton Synchrotron using the large acceptance NA61/SHINE hadron spectrometer. Spectra are presented as function of rapidity and transverse momentum and are compared to predictions of current models. [...]

Measurements of charged pion differential yields from the surface of the T2K replica target for incoming 31 GeV/c protons with the NA61/SHINE spectrometer at the CERN SPS / The NA61 collaboration
Measurements of particle emission from a replica of the T2K 90 cm-long carbon target were performed in the NA61/SHINE experiment at CERN SPS, using data collected during a high-statistics run in 2009. An efficient use of the long-target measurements for neutrino flux predictions in T2K requires dedicated reconstruction and analysis techniques [...]

Measurements of $\pi ^{\pm }$ , $K^{\pm }$ , $K^0_S$ , $\varLambda $ and proton production in proton–carbon interactions at 31 GeV/c with the NA61/SHINE spectrometer at the CERN SPS / NA61/SHINE Collaboration
Measurements of hadron production in p+C interactions at 31 GeV/c are performed using the NA61/ SHINE spectrometer at the CERN SPS. The analysis is based on the full set of data collected in 2009 using a graphite target with a thickness of 4% of a nuclear interaction length. [...]

Multiplicity and transverse momentum fluctuations in inelastic proton-proton interactions at the CERN Super Proton Synchrotron / NA61/SHINE Collaboration
Measurements of multiplicity and transverse momentum fluctuations of charged particles were performed in inelastic p+p interactions at 20, 31, 40, 80 and 158 GeV/c beam momentum. Results for the scaled variance of the multiplicity distribution and for three strongly intensive measures of multiplicity and transverse momentum fluctuations \$\Delta[P_{T},N]\$, \$\Sigma[P_{T},N]\$ and \$\Phi_{p_T}\$ are presented.

Design and Performance of the Data Acquisition System for the NA61/SHINE Experiment at CERN / Laszlo, Andras (Wigner RCP, Budapest) ; Denes, Ervin (Wigner RCP, Budapest) ; Fodor, Zoltan (Wigner RCP, Budapest) ; Kiss, Tivadar (Wigner RCP, Budapest) ; Kleinfelder, Stuart (UV, Irvine) ; Soos, Csaba (CERN) ; Tefelski, Dariusz (Warsaw U. of Tech.) ; Tolyhi, Tamas (Wigner RCP, Budapest) ; Vesztergombi, Gyorgy (Wigner RCP, Budapest) ; Wyszynski, Oskar (Jagiellonian U. ; CERN)
This paper describes the hardware, firmware and software systems used in data acquisition for the NA61/SHINE experiment at the CERN SPS accelerator. Special emphasis is given to the design parameters of the readout electronics for the 40 m^3 volume Time Projection Chamber detectors as these give the largest contribution to event data among all the subdetectors: events consisting of 8 bit ADC values from 256 time slices of 200 k electronic channels are to be read out with order of ~100 Hz readout rate.

NA61/SHINE facility at the CERN SPS: beams and detector system / NA61 collaboration
NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a multi-purpose experimental facility to study hadron production in hadron-proton, hadron-nucleus and nucleus-nucleus collisions at the CERN Super Proton Synchrotron. It recorded the first physics data with hadron beams in 2009 and with ion beams (secondary 7Be beams) in 2011. [...]
