13. Observation of Transverse Λ/Λ¯ Hyperon Polarization in e+e Annihilation at Belle / Guan, Y. ; Vossen, A. ; Adachi, I. ; Adamczyk, K. ; et al
We report the first observation of the spontaneous polarization of Λ and Λ¯ hyperons transverse to the production plane in e+e annihilation, which is attributed to the effect arising from a polarizing fragmentation function. [...]
