Lattice Computations of the Pion Form Factor
LHP Collaboration, Frederic D. R. Bonnet, Robert G. Edwards +3
We report on a program to compute the electromagnetic form factors of mesons. We discuss the techniques used to compute the pion form factor and present results computed with domai…
Hadronic physics with domain-wall valence and improved staggered sea quarks
D. B. Renner, W. Schroers, R. Edwards +6
With the advent of chiral fermion formulations, the simulation of light valence quarks has finally become realistic for numerical simulations of lattice QCD. The simulation of ligh…
Analysis of spectra using matrices of correlation functions based on irreducible baryon operators
LHP Collaboration, S. Basak, I. Sato +7
We present results for ground and excited-state nucleon masses in quenched lattice QCD using anisotropic lattices. Group theoretical constructions of local and nonlocal straight-li…
Baryonic sources using irreducible representations of the double-covered octahedral group
LHP Collaboration, S. Basak, R. Edwards +7
Irreducible representations (IRs) of the double-covered octahedral group are used to construct lattice source and sink operators for three-quark baryons. The goal is to achieve a g…
Calculating using HYP staggered fermions
Tanmoy Bhattacharya, George T. Fleming, Rajan Gupta +3
We present preliminary results for calculated using HYP staggered fermions in the quenched approximation. We compare different choices of quenched penguin operators.
Testing improved staggered fermions with and
Weonjong Lee, Tanmoy Bhattacharya, George T. Fleming +3
We study the improvement of staggered fermions using hypercubically smeared (HYP) links. We calculate the strange quark mass and the kaon B-parameter, , in quenched QCD on a $…
Finite Temperature QCD with Domain Wall Fermions
George Tamminga Fleming
Domain wall fermions are a new lattice fermion formulation which preserves the full chiral symmetry of the continuum at finite lattice spacing, up to terms exponentially small in a…
What can Lattice QCD theorists learn from NMR spectroscopists?
George T. Fleming
Euclidean-time hadron correlation functions computed in Lattice QCD (LQCD) are modeled by a sum of decaying exponentials, reminiscent of the exponentially damped sinusoid models of…
