We report on double-differential inclusive cross-sections of the production of secondary protons, charged pions, and deuterons, in the interactions with a 5% nuclear interaction length thick stationary copper target, of proton and pion beams with momentum from +/-3 GeV/c to +/-15 GeV/c. Results are given for secondary particles with production angles between 20 and 125 degrees.

Two-particle correlations in azimuthal angle and pseudorapidity in Be+Be
NA 61/SHINE实验旨在发现强相互作用物质的临界点，并研究解除禁闭开始的性质。通过测量质子-质子、质子-核和核-核相互作用中强子产生特性随碰撞能量和系统尺寸的变化，进行二维相图$(T-μ_B)$扫描，实现这些目标。本文首次给出了束流动量为20、30、40、75和150 GeV/c的Be+Be相互作用的赝快度和方位角的两粒子关联结果。NA 61/SHINE的结果将与已经提出的在类似束流动量下质子-质子碰撞的结果以及EPOS模型的结果进行比较
Distillation of scalar exchange by coherent hypernucleus production in antiproton-nucleus collisions
本文用束缚质子和$Λ$ -超子波函数的介子交换模型计算了束流动量为$1.5\div20$ GeV/c时相干过程$\bar p + {}^AZ \to {}^A_Λ(Z-1) + \barΛ$的总微分截面和角微分截面。结果表明，具有不同离散$Λ$态的超核产生截面的束流动量依赖关系的形状对$\bar p p \to \barΛΛ$振幅中标量$κ$ -介子交换的存在非常敏感.这可用作通过相干$\bar p A$反应中的标量$πK$相关性的交换的干净测试。
Measurements of Hadron Production in Pion-Carbon Interactions with NA61/SHINE at the CERN SPS
NA 61/SHINE是在CERN超级质子同步加速器上设计的一个固定靶实验，用于研究强子-质子、强子-核和核-核相互作用。在这一过程中，我们提出了在π介子-碳生产相互作用，这是根本的重要性，以改善广泛的空气簇射建模，从而解释超高能宇宙射线测量确定强子的光谱结果。特别是，我们的测量（反）重子和$ρ^0$生产的π-碳相互作用可以有助于改善预测的μ子生产的空气簇射模拟使用强子相互作用模型。在这篇文章中，我们讨论了数据分析和结果从介子-碳碰撞记录在束流动量为158和350 GeV/c。初步频谱的$K^{\pm}$和$p$（$\bar{p}$），以及比较预测的强子相互作用模型中使用的空气簇射模拟。此外，我们目前的最终结果的生产$ρ^0$，$ω$和$K^{0*}$共振。
