论文摘要
我们对Belle协作的实验数据进行了彻底的现象学分析，用于横向$λ$和$ \ \barλ$极化，以$ e^+e^ - $ nihilation Processes测量，用于包容性（加上JET）的情况（加JET）及其相关的生产，并带有轻型的强子。这允许对$λ$ Hyperon的夸克极化片段化函数进行第一次提取，这是横向动量依赖性分布，从而使未极化的夸克片段成横向极化的spin-1/2强体。
We present a thorough phenomenological analysis of the experimental data from Belle Collaboration for the transverse $Λ$ and $\barΛ$ polarisation, measured in $e^+e^-$ annihilation processes, for the case of inclusive (plus a jet) and associated production with a light charged hadron. This allows for the first ever extraction of the quark polarising fragmentation function for a $Λ$ hyperon, a transverse momentum dependent distribution giving the probability that an unpolarised quark fragments into a transversely polarised spin-1/2 hadron.
