Determination of - and -wave scattering amplitudes in lattice QCD
Ruairí Brett, John Bulava, Jacob Fallica +3
The elastic , - and -wave kaon-pion scattering amplitudes are calculated using a single ensemble of anisotropic lattice QCD gauge field configurations with $N_{\mathrm…
Towards string breaking with 2+1 dynamical fermions using the stochastic LapH method
Vanessa Koch, John Bulava, Ben Hörz +4
We investigate the use of stochastically estimated light quark propagators in correlation functions involving a static color source. To this end we compute the static-light meson p…
Non-perturbative improvement of the axial current in N_f=3 lattice QCD with Wilson fermions and tree-level improved gauge action
John Bulava, Michele Della Morte, Jochen Heitger +1
The coefficient c_A required for O(a) improvement of the axial current in lattice QCD with N_f=3 flavors of Wilson fermions and the tree-level Symanzik-improved gauge action is det…
On the computation of hadron-to-hadron transition matrix elements in lattice QCD
John Bulava, Michael Donnellan, Rainer Sommer
We discuss the accurate determination of matrix elements < f| h_w | i > where neither |i> nor |f> is the vacuum state and h_w is some operator. Using solutions of the Generalized E…
Stochastic All-to-All Propagators for Baryon Correlators
John Bulava, Robert Edwards, Colin Morningstar
The effectiveness of various dilution schemes in the evaluation of baryonic two-point functions is compared. The error of a representative set of observables as a function of the n…
