Nucleon-sigma terms at with a variational analysis from lattice QCD
Lorenzo Barca, Gunnar Bali, Sara Collins +1
Nucleon sigma terms are important for the decomposition of the nucleon mass and for searches for new physics beyond the Standard Model involving scalar interactions. A persistent t…
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…
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…
Pion structure from lattice QCD
G. Bali, S. Collins, B. Glässle +5
We report on the lowest moment of parton distribution functions and generalized form factors for the pion at several values of the momentum transfer. Calculations are performed for…
Moments of structure functions for near the physical point
G. S. Bali, S. Collins, B. Gläßle +7
We report on our on-going study of the lower moments of iso-vector polarised and unpolarised structure functions, and , respectively, and the iso-vect…
An Update on Distribution Amplitudes of the Nucleon and its Parity Partner
R. W. Schiel, G. S. Bali, V. M. Braun +12
The calculation of baryon wave functions at small inter-quark separations is an ongoing effort within the QCDSF collaboration. In this update on normalization constants and distrib…
Disconnected contributions to D-meson semi-leptonic decay form factors
G. S. Bali, S. Collins, R. Horsley +9
We calculate the disconnected contribution to the form factor for the semileptonic decay of a D-meson into a final state, containing a flavor singlet eta meson. We use QCDSF n_f=2+…
