Novel Structure Function for Photon Fragmentation into a $\Lambda$ Hyperon and Transverse $\Lambda$ Polarization in Unpolarized Electron-Positron Annihilation
The possibility is examined for the inclusive Λ 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 Λ hyperon (or any other baryons) production from the unpolarized time-like photon fragmentation, which makes contribution to the transverse Λ polarization in the unpolarized electron-positron annihilation.
