Determination of the Delta resonance width from lattice QCD
C. Alexandrou, J. W. Negele, M. Petschlies
A method suitable for extracting resonance parameters of unstable baryons in lattice QCD is examined. The method is applied to the strong decay of the Delta to a pion-nucleon state…
Lattice study of the Boer-Mulders transverse momentum distribution in the pion
M. Engelhardt, B. Musch, P. Hägler +2
The Boer-Mulders transverse momentum-dependent parton distribution (TMD) characterizes polarized quark transverse momentum in an unpolarized hadron. Techniques previously developed…
Axial Nucleon and Nucleon to Delta form fractors and the Goldberger-Treiman Relations from Lattice QCD
C. Alexandrou, G. Koutsou, Th. Leontiou +2
We evaluate the nucleon axial form factor, , and induced pseudoscalar form factor, , as well as the pion-nucleon form factor, , in lattice QCD. W…
The eta ' signal from partially quenched Wilson fermions
Harmut Neff, Th. Lippert, J. W. Negele +1
We present new results from our ongoing study of flavor singlet pseudoscalar mesons in QCD. Our approach is based on (a) performing truncated eigenmode expansions for the hairpin d…
