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…
A lattice study of the strangeness content of the nucleon
G. S. Bali, S. Collins, M. Gockeler +9
We determine the quark contributions to the nucleon spin Delta s, Delta u and Delta d as well as their contributions to the nucleon mass, the sigma-terms. This is done by computing…
Spectra of heavy-light and heavy-heavy mesons containing charm quarks, including higher spin states for
G. Bali, S. Collins, S. Durr +18
We study the spectra of heavy-light and heavy-heavy mesons containing charm quarks, including higher spin states. We use two sets of gauge configurations, one set fro…
Dirac and Pauli form factors from lattice QCD
S. Collins, M. Göckeler, Ph. Hägler +11
We present a comprehensive analysis of the electromagnetic form factors of the nucleon from a lattice simulation with two flavors of dynamical O(a)-improved Wilson fermions. A key…
Disconnected contributions to hadronic structure: a new method for stochastic noise reduction
S. Collins, G. Bali, A. Schäfer
We present a new method for reducing the stochastic noise of all-to-all propagators based on stopping the inversion of the propagator before convergence. The method is easy to impl…
Upsilon and J/Psi Spectroscopy Using Clover Fermions in the Presence of Dynamical Quarks
Sara Collins, Robert G. Edwards, Urs M. Heller +1
We calculate spin averaged splittings in the bottomonium and charmonium systems using the clover action. We compare static and kinetic masses of heavy-heavy and heavy-light mesons…
