Octet baryon isovector charges from lattice QCD
Gunnar S. Bali, Sara Collins, Simon Heybrock +4
We determine the axial, scalar and tensor isovector charges of the nucleon, sigma and cascade baryons as well as the difference between the up and down quark masses, . We…
Mellin moments of spin dependent and independent PDFs of the pion and rho meson
Marius Löffler, Philipp Wein, Thomas Wurm +5
We compute the second moments of pion and rho parton distribution functions (PDFs) in lattice QCD with flavors of improved Wilson fermions. We determine both singlet an…
Baryonic and mesonic 3-point functions with open spin indices
Gunnar S. Bali, Sara Collins, Benjamin Glässle +5
We have implemented a new way of computing three-point correlation functions. It is based on a factorization of the entire correlation function into two parts which are evaluated w…
Nucleon generalized form factors from lattice QCD with nearly physical quark masses
Gunnar Bali, Sara Collins, Meinulf Göckeler +3
We determine generalized form factors of the nucleon from lattice simulations with mass-degenerate non-perturbatively improved Wilson-Sheikholeslami-Wohlert fermions down…
Can Baryon Chiral Perturbation Theory be used to extrapolate lattice data for the moment of the nucleon?
Peter C. Bruns, Ludwig Greil, Rudolf Rödl +1
We discuss the question in the title employing manifestly covariant Baryon Chiral Perturbation Theory and recent high-statistics lattice results published in [1].
The moment of the nucleon from lattice QCD down to nearly physical quark masses
Gunnar S. Bali, Sara Collins, Benjamin Gläßle +7
We present an update of our analysis [1] which includes additional ensembles at different quark masses, lattice spacings and volumes, all with high statistics. We use mass-…
Nucleon generalized form factors and sigma term from lattice QCD near the physical quark mass
G. S. Bali, S. Collins, B. Gläßle +8
We present new N_f=2 data for the nucleon generalized form factors, varying volume, lattice spacing and pion mass, down to 150 MeV. We also give an update of our direct calculation…
Nucleon structure from stochastic estimators
Gunnar S. Bali, Sara Collins, Benjamin Gläßle +6
Using stochastic estimators for connected meson and baryon three-point functions has successfully been tried in the past years. Compared to the standard sequential source method we…
Topological zero modes at nonzero chemical potential
Falk Bruckmann, Rudolf Rodl, Tin Sulejmanpasic
We give analytical and numerical solutions for the zero modes of the Dirac operator in topological SU(2) gauge backgrounds at nonzero chemical potential. Continuation from imaginar…
