Nucleon distribution amplitudes and proton decay matrix elements on the lattice (2008)
Braun, V. M., Göckeler, M., Horsley, R., Kaltenbrunner, T., Nakamura, Y., Pleiter, D., ...
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 within lattice QCD. In...
Clover improvement for stout-smeared 2+1 flavour SLiNC fermions: non-perturbative results (2008)
Cundy, N., Göckeler, M., Horsley, R., Kaltenbrunner, T., Kennedy, A. D., Nakamura, Y., ...
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) Symanzik improved gluon...
Non-perturbative renormalization of three-quark operators (2008)
Göckeler, M., Horsley, R., Kaltenbrunner, T., Nakamura, Y., Pleiter, D., Rakow, P. E. L., ...
High luminosity accelerators have greatly increased the interest in semi-exclusive and exclusive reactions involving nucleons. The relevant theoretical information is contained in the nucleon...
Moments of nucleon distribution amplitudes from irreducible three-quark operators (2007)
Göckeler, M., Horsley, R., Kaltenbrunner, T., Nakamura, Y., Pleiter, D., Rakow, P. E. L., ...
Semi-exclusive and exclusive processes are becoming more and more important in high energy physics since they are excellently suited to study the internal hadronic structure. To analyze such...
