Structure of the Nucleon
M. Göckeler, T. R. Hemmert, R. Horsley +5
Generalized parton distributions provide information on the longitudinal and transverse distribution of partons in the fast moving nucleon. Furthermore, they contain information on…
Moments of nucleon spin-dependent generalized parton distributions
W. Schroers, R. C. Brower, P. Dreher +10
We present a lattice measurement of the first two moments of the spin-dependent GPD H-tilde(x,xi,t). From these we obtain the axial coupling constant and the second moment of the s…
transition form factors in Quenched and QCD
C. Alexandrou, Ph. de Forcrand, Th. Lippert +5
Calculations of the magnetic dipole, electric quadrupole and Coulomb quadrupole amplitudes for the transition are presented both in quenched QCD and with two flavours of…
N to Delta electromagnetic transition form factors from Lattice QCD
C. Alexandrou, Ph. de Forcrand, Th. Lippert +5
The magnetic dipole, the electric quadrupole and the Coulomb quadrupole amplitudes for the transition are evaluated both in quenched lattice QCD at and using two…
Advanced Algorithms for the Simulation of Gauge Theories with Dynamical Fermionic Degrees of Freedom
Wolfram Schroers
This thesis is focused on the implementation and the application of a novel kind of algorithm which is expected to overcome the limitations of older schemes. This new algorithm is…
Generalized Parton Distributions from Lattice QCD
M. Göckeler, R. Horsley, D. Pleiter +4
We perform a quenched lattice calculation of the first moment of twist-two generalized parton distribution functions of the proton, and assess the total quark (spin and orbital ang…
