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…
Exploring the Spectrum of QCD using the Lattice
John Bulava, Saul Cohen, Jozef Dudek +14
The calculation of the spectrum of QCD is key to an understanding of the strong interactions, and vital if we are to capitalize on the experimental study of the spectrum. In this p…
Bottom-Hadron Mass Splittings from Static-Quark Action on 2+1-Flavor Lattices
Huey-Wen Lin, Saul D. Cohen, Nilmani Mathur +1
We calculate bottom-hadron mass splittings with respect to and using full QCD with 2+1 flavors of dynamical Kogut-Susskind sea quarks and domain-wall valence quarks alo…
Challenges in Hadronic Form Factor Calculations
Huey-Wen Lin, Saul D. Cohen, Robert G. Edwards +2
There is an extensive history of form factor calculations on the lattice, primarily with ground states for both initial and final states. However, there have never been any radiall…
First results from 2+1 dynamical quark flavors on an anisotropic lattice: light-hadron spectroscopy and setting the strange-quark mass
Huey-Wen Lin, Saul D. Cohen, Jozef Dudek +12
We present the first light-hadron spectroscopy on a set of dynamical, anisotropic lattices. A convenient set of coordinates that parameterize the two-dimensional plane of…
First Lattice Study of the - Transition Form Factors
Huey-Wen Lin, Saul D. Cohen, Robert G. Edwards +1
Experiments at Jefferson Laboratory, MIT-Bates, LEGS, Mainz, Bonn, GRAAL, and Spring-8 offer new opportunities to understand in detail how nucleon resonance () properties emer…
