Improved Light-Cone Sum Rules for the Electromagnetic Form Factors of the Nucleon
Alexander Lenz, Markus Wittmann, Eckart Stein
We calculate the electromagnetic form factors of the nucleon within the light-cone sum rule approach. In comparison to previous work (hep-ph/0112085) we suggest to use a pure isosp…
Higher Twist Distribution Amplitudes of the Nucleon in QCD
V. Braun, R. J. Fries, N. Mahnke +1
We present the first systematic study of higher-twist light-cone distribution amplitudes of the nucleon in QCD. We find that the valence three-quark state is described at small tra…
Nuclear Enhanced Higher-Twist Effects in the Drell-Yan Process
R. J. Fries, A. Schäfer, E. Stein +1
We calculate the Drell-Yan cross section, resolving the full kinematics of the lepton pair, at high transverse momentum for hadron nucleus collisions. We use the general framework…
Angular Dependence of the Nuclear Enhancement of Drell-Yan Pairs
R. J. Fries, B. Müller, A. Schäfer +1
We calculate the nuclear enhancement in the angular distribution of Drell-Yan pairs produced in proton-nucleus reactions. Nuclear effects are encoded in universal twist-4 parton co…
Higher-twist contributions in exclusive processes
M. Vänttinen, L. Mankiewicz, E. Stein
Using the renormalon technique, we estimate higher-twist contributions in deeply virtual Compton scattering and in hard exclusive leptoproduction.
Renormalon Model Predictions for Power-Corrections to Flavour Singlet Deep Inelastic Structure Functions
E. Stein, M. Maul, L. Mankiewicz +1
We analyze power corrections to flavour singlet deep inelastic scattering structure functions in the framework of the infrared renormalon model. Our calculations, together with pre…
