Spin-dependent structure functions ${\hat{g}}_1$ and ${\hat{g}}_2$ for inclusive spin-half baryon production in electron-positron annihilation

Abstract

Two spin-dependent structure functions ${\hat{g}}_1$ and ${\hat{g}}_2$ for the inclusive spin-half baryon production in electron-positron annihilation are studied in the context of QCD factorization as well as in the naive quark parton model. As a result, it is found that the sum of ${\hat{g}}_1$ and ${\hat{g}}_2$ is related to ${\hat{h}}_1$ and ${\hat{g}}_T$, two quark fragmentation functions defined by Jaffe and Ji. In connection with the measurement of quark fragmentation functions, the possible phenomenological consequences are discussed.
