Nucleon sigma terms with a variational analysis from Lattice QCD
Lorenzo Barca, Gunnar Bali, Sara Collins
We determine the nucleon-sigma terms from lattice QCD. We find that the dominant excited state contamination in the nucleon three-point function with a scalar current is due to the…
Updated determination of light-cone distribution amplitudes of octet baryons in lattice QCD
G. S. Bali, V. M. Braun, S. Bürger +6
We present updated results on the wave function normalization constants and the first moments of the light cone distribution amplitudes for the lowest-lying baryon octet. The analy…
Progress on nucleon transition matrix elements with a lattice QCD variational analysis
Lorenzo Barca, Gunnar Bali, Sara Collins
Nucleon weak matrix elements can be extracted from nucleon correlation functions with lattice QCD simulations. The signal-to-noise ratio prohibits the analysis at large source-sink…
Nonperturbative Renormalization in Lattice QCD with three Flavors of Clover Fermions: Using Periodic and Open Boundary Conditions
G. S. Bali, S. Bürger, S. Collins +6
We present the nonperturbative computation of renormalization factors in the RI'-(S)MOM schemes for the QCD gauge field ensembles generated by the CLS (coordinated lattice simulati…
Non-perturbative renormalization of flavor singlet quark bilinear operators in lattice QCD
G. S. Bali, S. Collins, M. Göckeler +2
We report on our studies of the renormalization of flavor singlet quark bilinear operators in lattice QCD. The renormalization constants are determined non-perturbatively using gau…
Local CP-violation and electric charge separation by magnetic fields from lattice QCD
G. S. Bali, F. Bruckmann, G. Endrodi +3
We study local CP-violation on the lattice by measuring the local correlation between the topological charge density and the electric dipole moment of quarks, induced by a constant…
