Exploring strange nucleon form factors on the lattice
Ronald Babich, Richard C. Brower, Michael A. Clark +4
We discuss techniques for evaluating sea quark contributions to hadronic form factors on the lattice and apply these to an exploratory calculation of the strange electromagnetic, a…
Multigrid solver for clover fermions
J. C. Osborn, R. Babich, J. Brannick +4
We present an adaptive multigrid Dirac solver developed for Wilson clover fermions which offers order-of-magnitude reductions in solution time compared to conventional Krylov solve…
Better HMC integrators for dynamical simulations
M. A. Clark, Balint Joo, A. D. Kennedy +1
We show how to improve the molecular dynamics step of Hybrid Monte Carlo, both by tuning the integrator using Poisson brackets measurements and by the use of force gradient integra…
Parallelizing the QUDA Library for Multi-GPU Calculations in Lattice Quantum Chromodynamics
Ronald Babich, Michael A. Clark, Bálint Joó
Graphics Processing Units (GPUs) are having a transformational effect on numerical lattice quantum chromodynamics (LQCD) calculations of importance in nuclear and particle physics.…
Parity Doubling and the S Parameter Below the Conformal Window
Thomas Appelquist, Ron Babich, Richard C. Brower +11
We describe a lattice simulation of the masses and decay constants of the lowest-lying vector and axial resonances, and the electroweak S parameter, in an SU(3) gauge theory with $…
Adaptive multigrid algorithm for the lattice Wilson-Dirac operator
R. Babich, J. Brannick, R. C. Brower +5
We present an adaptive multigrid solver for application to the non-Hermitian Wilson-Dirac system of QCD. The key components leading to the success of our proposed algorithm are the…
