The first measurements of light antinucleus production in Au+Au collisions at RHIC are reported. The observed production rates for antideuterons and antihelions are much larger than in lower energy ...nucleus-nucleus collisions. A coalescence model analysis of the yields indicates that there is little or no increase in the antinucleon freeze-out volume compared to collisions at SPS energy. These analyses also indicate that the antihelion freeze-out volume is smaller than the antideuteron freeze-out volume.

Eur. Phys. J. C (2016) 76: 617 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.
Eur. Phys. J. C (2016) 76: 198 Inclusive production of $\Lambda$-hyperons was measured with the large
acceptance NA61/SHINE spectrometer at the CERN SPS in inelastic p+p
interactions at beam momentum ...of 158~\GeVc. 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
$0.120\,\pm0.006\;(stat.)\,\pm 0.010\;(sys.)$. The results are compared with
previous measurements and predictions of the EPOS, UrQMD and FRITIOF models.
The European Physical Journal C, 76(2), 1-49 (2016) 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. Inelastic and production cross
sections as well as spectra of $\pi^\pm$, $K^\pm$, p, $K^0_S$ and $\Lambda$ are
measured with high precision. These measurements are essential for improved
calculations of the initial neutrino fluxes in the T2K long-baseline neutrino
oscillation experiment in Japan. A comparison of the NA61/SHINE measurements
with predictions of several hadroproduction models is presented.
