Nucleon distribution amplitudes and proton decay matrix elements on the lattice
V. M. Braun, M. Göckeler, R. Horsley +9
Baryon distribution amplitudes (DAs) are crucial for the theory of hard exclusive reactions. We present a calculation of the first few moments of the leading-twist nucleon DA withi…
Clover improvement for stout-smeared 2+1 flavour SLiNC fermions: non-perturbative results
N. Cundy, M. Göckeler, R. Horsley +11
We discuss an action in which the fermion matrix has single level stout smearing for the hopping terms together with unsmeared links for the clover term. With the (tree level) Syma…
Wave functions of the nucleon and its parity partner from lattice QCD
Nikolaus Warkentin, Vladimir M. Braun, Meinulf Göckeler +9
We compute moments of distribution amplitudes using gauge configurations with two flavors of clover fermions from QCDSF/DIK and operators which are optimized with respect to their…
Non-perturbative renormalization of three-quark operators
M. Göckeler, R. Horsley, T. Kaltenbrunner +8
High luminosity accelerators have greatly increased the interest in semi-exclusive and exclusive reactions involving nucleons. The relevant theoretical information is contained in…
Status of the QPACE Project
H. Baier, H. Boettiger, M. Drochner +27
We give an overview of the QPACE project, which is pursuing the development of a massively parallel, scalable supercomputer for LQCD. The machine is a three-dimensional torus of id…
Nucleon structure in terms of OPE with non-perturbative Wilson coefficients
W. Bietenholz, N. Cundy, M. Gockeler +7
Lattice calculations could boost our understanding of Deep Inelastic Scattering by evaluating moments of the Nucleon Structure Functions. To this end we study the product of electr…
