Transverse $\Lambda^0$ polarization in inclusive quasi-real photoproduction at the current fragmentation

TL;DR

This paper explains the transverse polarization of Lambda0 particles observed in quasi-real photoproduction using the strange quark scattering model, linking it to quark recombination theories.

Contribution

It demonstrates that the strange quark scattering model can account for recent experimental polarization data and discusses its relation to quark recombination approaches.

Findings

Strange quark scattering model fits HERMES data on Lambda0 polarization.

Discussion of connections between scattering model and quark recombination.

Provides theoretical explanation for observed polarization phenomena.

Abstract

It is shown that the recent HERMES data on the transverse $\Lambda^0$ polarization in the inclusive quasi-real photoproduction at $x_F>0$ can be accommodated by the strange quark scattering model. Relations with the quark recombination approach are discussed.
