Fragmentation contributions to transverse nucleon spin observables in semi-inclusive deep-inelastic scattering at NLO

Diego Scantamburlo, Marc Schlegel

We study the spin-dependent cross section in semi-inclusive deep-inelastic lepton-nucleon collisions, $\ell +N^{\uparrow }\to \ell +h+X$. We focus on the cross section that is integra…
