hyperon polarization in 
annihilation at BelleGuan, Y.*; Tanida, Kiyoshi 
; Belle Collaboration*; 205 of others*
We report the first observation of the spontaneous polarization of 
and 
hyperons transverse to the production plane in annihilation, which is attributed to the effect arising from a polarizing fragmentation function. For inclusive production, we also report results with subtracted feed-down contributions from 
and charm. This measurement uses a dataset of 800.4 fb
collected by the Belle experiment at or near a center-of-mass energy of 10.58 GeV. We observe a significant polarization that rises with the fractional energy carried by the hyperon.
