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…
Theoretical Uncertainties in the QCD Evolution of Structure Functions and their Impact on
J. Blümlein, S. Riemersma, W. L. van Neerven +1
The differences are discussed between various next-to-leading order prescriptions for the QCD evolution of parton densities and structure functions. Their quantitative impact is un…
The Evolution of Unpolarized and Polarized Structure Functions at Small
J. Blümlein, S. Riemersma, A. Vogt
A survey is given of recent developments on the resummed small- evolution, in a framework based on the renormalization group equation, of non--singlet and singlet structure func…
On Small-x Resummations for the Evolution of Unpolarized and Polarized Non--Singlet and Singlet Structure Functions
J. Blümlein, S. Riemersma, A. Vogt
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
P. Aurenche, G. A. Schuler, A. Bawa +41
This report is an overview of the gamma-gamma physics capabilities of LEP2, and covers the following topics: structure functions, equivalent photon approximation, tagging condition…
