Inclusive production of hadrons in ${\ell }^{\uparrow }{p}^{\uparrow }\to h^{\uparrow }X$ and spin measurements

M. Anselmino, M. Boglione, J. Hansson +1

We discuss the production of polarized hadrons in polarized lepton nucleon interactions and show that the helicity density matrix of the hadron, when measurable, can give informati…
