On the Resummation of the epe^+e^-$ Annihilation
J. Blümlein, S. Riemersma, A. Vogt
The resummation of the non-singlet contributions is performed for initial state QED corrections. As examples, the effect of the resummation on neutral-current deep-inel…
The Small-x Evolution of Unpolarized and Polarized Structure Functions
J. Blümlein, S. Riemersma, A. Vogt
A brief overview is presented of recent developments concerning resummed small-x evolution, based upon the renormalization group equation. The non-singlet and singlet structure fun…
The Heavy-Flavour Contribution to Proton Structure
K. Daum, S. Riemersma, B. W. Harris +2
We present theoretical and experimental considerations pertaining to deeply inelastic heavy-flavour production at HERA. The various theoretical uncertainties in the cross section c…
A Detailed Comparison of NLO QCD Evolution Codes
J. Blümlein, M. Botje, C. Pascaud +4
Seven next-to-leading order QCD evolution programs are compared. The deviations of the results due to different theoretical prescriptions for truncating the perturbative series are…
QCD corrections to
J. Blümlein, S. Riemersma
We perform a numerical study of the QCD corrections to the structure function in the HERA energy range. The --factors are of and larger in parts of the kin…
Deep-inelastic production of heavy quarks
E. Laenen, M. Buza, B. W. Harris +5
Deep-inelastic production of heavy quarks at HERA, especially charm, is an excellent signal to measure the gluon distribution in the proton at small values. By measuring variou…

A brief survey is given of recent results on the resummation of leading small-x terms for unpolarized and polarized non--singlet and singlet structure function evolution.
Heavy-Quark Production in Scattering
Eric Laenen, Stephan Riemersma
Open heavy flavour production at colliders in deeply inelastic scattering has an interesting feature: the structure function for this process is calculab…
Gamma-Gamma Physics at LEP2
