Spectra are presented as function of rapidity and transverse momentum and are compared to predictions of current models. The measurements serve as the baseline in the NA61/SHINE study of the properties of the onset of deconfinement and search for the critical point of strongly interacting matter.
NA61/SHINE CollaborationMeasurements of $$\pi ^\pm $$ π ± , $$K^\pm $$ K ± and proton double differential yields from the surface of the T2K replica target for incoming 31 GeV/c protons with the NA61/SHINE spectrometer at the CERN SPSN. Abgrall, A. Aduszkiewicz, Evgeny Andronov et al.|The European Physical Journal C|2019 Measurements of the , K , 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 yields were measured with increased precision compared to the previously published NA61/SHINE results, while the K and proton yields were obtained for the first time. A strategy for dealing with the dependence of the results on the incoming proton beam profile is proposed. The purpose of these measurements is to reduce significantly the (anti)neutrino flux uncertainty in the T2K longbaseline neutrino experiment by constraining the production of (anti)neutrino ancestors coming from the T2K target.
Measurements of $$\pi ^\pm $$ π ± differential yields from the surface of the T2K replica target for incoming 31 GeV/c protons with the NA61/SHINE spectrometer at the CERN SPSN. Abgrall, A. Aduszkiewicz, M. Ajaz et al.|The European Physical Journal C|2016 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. Fully-corrected differential yields of $$\pi ^\pm $$ -mesons from the surface of the T2K replica target for incoming 31 GeV/c protons are presented. A possible strategy to implement these results into the T2K neutrino beam predictions is discussed and the propagation of the uncertainties of these results to the final neutrino flux is performed.
Production of $$\Lambda $$ Λ -hyperons in inelastic p+p interactions at 158 $${\mathrm{GeV}}\!/\!c$$ GeV / cA. Aduszkiewicz, Y. Ali, Evgeny Andronov et al.|The European Physical Journal C|2016 Inclusive production of -hyperons was measured with the large acceptance NA61/SHINE spectrometer at the CERN SPS in inelastic p+p interactions at beam momentum of 158 GeV/c. Spectra of transverse momentum and transverse mass as well as distributions of rapidity and x F are presented. The mean multiplicity was estimated to be 0.120 0.006 (stat.) 0.010 (sys.). The results are compared with previous measurements and predictions of the Epos, Urqmd and Fritiof models.
