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…
Scale setting and the light baryon spectrum in QCD with Wilson fermions
Gunnar S. Bali, Sara Collins, Peter Georg +7
We determine the light baryon spectrum on ensembles generated by the Coordinated Lattice Simulations (CLS) effort, employing flavours of non-perturbatively improved Wilso…
Scale Setting for CLS 2+1 Simulations
Ben Straßberger, Marco Cè, Sara Collins +9
We present an update of the scale setting for flavor QCD using gradient flow scales and pseudo-scalar decay constants. We analyze the latest ensembles with flavors…
Hadro-quarkonium from Lattice QCD
Maurizio Alberti, Gunnar S. Bali, Sara Collins +3
The hadro-quarkonium picture [S. Dubinskiy and M.B. Voloshin, Phys. Lett. B 666, 344 (2008)] provides one possible interpretation for the pentaquark candidates with hidden charm, r…
Direct determinations of the nucleon and pion terms at nearly physical quark masses
Gunnar S. Bali, Sara Collins, Daniel Richtmann +3
We present a high statistics study of the pion and nucleon light and strange quark sigma terms using dynamical non-perturbatively improved clover fermions with a range of p…
Simulation of QCD with N_f=2+1 flavors of non-perturbatively improved Wilson fermions
Mattia Bruno, Dalibor Djukanovic, Georg P. Engel +11
We describe a new set of gauge configurations generated within the CLS effort. These ensembles have N_f=2+1 flavors of non-perturbatively improved Wilson fermions in the sea with t…
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-…
Light-cone Distribution Amplitudes of the Nucleon and Negative Parity Nucleon Resonances from Lattice QCD
V. M. Braun, S. Collins, B. Gläßle +6
We present the results of a lattice study of light-cone distribution amplitudes (DAs) of the nucleon and negative parity nucleon resonances using two flavors of dynamical (clover)…
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…
Thermal mass and dispersion relations of quarks in the deconfined phase of quenched QCD
Olaf Kaczmarek, Frithjof Karsch, Masakiyo Kitazawa +1
Temporal quark correlation functions are analyzed in quenched lattice QCD for two values of temperature above the critical temperature (Tc) for deconfinement, T=1.5Tc and 3Tc. A tw…
Chiral symmetry restoration and the Z3 sectors of QCD
Christof Gattringer, P. E. L. Rakow, Andreas Schaefer +1
Quenched SU(3) lattice gauge theory shows three phase transitions, namely the chiral, the deconfinement and the Z3 phase transition. Knowing whether or not the chiral and the decon…
Calorons and localization of quark eigenvectors in lattice QCD
M. Göckeler, P. E. L. Rakow, A. Schäfer +2
We analyze the localization properties for eigenvectors of the Dirac operator in quenched lattice QCD in the vicinity of the deconfinement phase transition. Studying the characteri…
