Transverse ? polarization in e+e? collisions

In this paper we study transverse polarization of ? hyperons in single-inclusive leptonic annihilation. We show that when the momentum baryon is measured with respect to thrust axis, a dependent (TMD) factorization formalism required and generated by TMD polarizing fragmentation function (TMD PFF), D1T?. However, initial leptons, collinear twist-3 intrinsic DT. Thus while these measurements differ from one another only change measurement they probe different distribution functions. Recently, Belle significant production as axis. data can principle be re-analyzed measure lepton pair. This observable could first function, paper, develop for polarization; then present recent was established describe polarization. Using formalism, demonstrate at OPAL described using twist-2 formalism. Finally, make theoretical prediction Belle.
