An NLO calculation of the electroproduction of large-E $_{\bot}$ hadrons

We present a next-to-leading order calculation of the cross section for the leptoproduction of large-\(E_{\bot}\) hadrons and we compare our predictions with H1 data on the forward production of \({\rm\pi}^0\). We find large higher order corrections and an important sensitivity to the renormalizatio...

Summary:We present a next-to-leading order calculation of the cross section for the leptoproduction of large-\(E_{\bot}\) hadrons and we compare our predictions with H1 data on the forward production of \({\rm\pi}^0\). We find large higher order corrections and an important sensitivity to the renormalization and factorization scales. These large corrections are shown to arise in part from BFKL-like diagrams at the lowest order.
