Probing Quark Fragmentation Functions for Spin-1/2 Baryon Production in Unpolarized $e^{+}{e}^{-}$ Annihilation

Kun Chen, Gary R. Goldstein, R. L. Jaffe +1

We study the measurement of the quark fragmentation functions for spin-1/2 baryon production ($\Lambda$ and $\bar{\Lambda }$, in particular) in unpolarized $e^{+}{e}^{-}$ annihilation. The spin-depend…
