Spin-dependent nonsinglet structure functions in next-to-leading order
Spin-dependent nonsinglet structure functions in next-to-leading order
We study in detail the flavor-nonsinglet component of polarized structure functions in the framework of a consistent and complete next-to-leading order [O(${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$)] analysis. In this context, we discuss some important features of the calculation of the next-to-leading order corrections. Particular emphasis is put on the ${\mathit{Q}}^{2}$ evolution of sum rules …
