Novel Structure Function for Photon Fragmentation into a Hyperon and Transverse Polarization in Unpolarized Electron-Positron Annihilation
Abstract
The possibility is examined for the inclusive in unpolarized electron-positron annihilation to be transversely polarized. Due to final-state interactions, there exists a novel structure function F(z,Q2) for the inclusive hyperon (or any other baryons) production from the unpolarized time-like photon fragmentation, which makes contribution to the transverse polarization in the unpolarized electron-positron annihilation.
