论文摘要
我们研究了Cabibbo的特性，抑制了$λ$的准生产和$σ$ Hyperos与Nuclei的抗肿瘤相互作用，包括修饰的外形轴向质量，第二类电流和SU（3）风味的效果。超子和核子受到核电位的影响，并且传出的超子可以进行最终状态相互作用。超子电位通过吸收对其产量产生了重大影响。我们预测，与其他超子生产渠道相比，通过$σ\至λ$转换将有明显的增强$λ$的产生。我们通过将现实的中微子能量分布与合适的核靶标相结合，为多种实验产生预测。
We study the properties of the Cabibbo suppressed quasielastic production of $Λ$ and $Σ$ hyperons in antineutrino interactions with nuclei, including the effects of modified form factor axial mass, the second class current and SU(3) flavour violations. The hyperon and nucleon are subjected to the nuclear potential and the outgoing hyperon can undergo final state interactions. The hyperon potential has a significant effect on their production through absorption. We predict a significant enhancement of $Λ$ production compared with other hyperon production channels through $Σ\to Λ$ conversions. We produce predictions for several experiments by combining realistic neutrino energy distributions with suitable nuclear targets.
