Nucleon structure from generalized parton distributions in lattice QCD
M. Gockeler, Ph. Hagler, R. Horsley +5
This talk presents results from the QCDSF-UKQCD collaboration for moments of leading twist generalized parton distributions in two-flavor lattice QCD based on O(a) improved Wilson…
The axial charge of the nucleon on the lattice and in chiral perturbation theory
A. Ali Khan, M. Göckeler, P. Hägler +10
We present recent Monte Carlo data for the axial charge of the nucleon obtained by the QCDSF-UKQCD collaboration for N_f=2 dynamical quarks. We compare them with formulae from chir…
Evolution Equation for Generalized Parton Distributions
M. Kirch, A. Manashov, A. Schafer
The extension of the method [arXiv:hep-ph/0503109] for solving the leading order evolution equation for Generalized Parton Distributions (GPDs) is presented. We obtain the solution…
Complex conformal spin partial wave expansion of generalized parton distributions and distribution amplitudes
D. Müller, A. Schäfer
We introduce a new representation of generalized parton distributions and generalized distribution amplitudes that is based on the partial wave decomposition with respect to the co…
Topologically non-trivial field configurations - interplay of vortices and Dirac eigenmodes
Stefan Solbrig, Jochen Gattnar, Christof Gattringer +4
Gluon field configurations with non-trivial topology like instantons, magnetic monopoles and center vortices play a crucial role in QCD and, in particular, for the spontaneous brea…
Solving the leading order evolution equation for GPDs
A. Manashov, M. Kirch, A. Schafer
An analytic method for the solution of the evolution equation for GPDs is presented. The small x, xi asymptotics of GPDs are calculated.
