Mesonic Form Factors
LHPC Collaboration, Frederic D. R. Bonnet, Robert G. Edwards +3
We have started a program to compute the electromagnetic form factors of mesons. We discuss the techniques used to compute the pion form factor and present preliminary results comp…
Baryon operators and spectroscopy in lattice QCD
LHP Collaboration, S. Basak, R. Edwards +7
The construction of the operators and correlators required to determine the excited baryon spectrum is presented, with the aim of exploring the spatial and spin structure of the st…
The pion electromagnetic form factor
Frederic D. R. Bonnet, Robert G. Edwards, George T. Fleming +2
A ratio of lattice correlation functions is identified from which the pion form factor can be obtained directly. Preliminary results from quenched Wilson simulations are presented.
Mass spectrum of N* and source optimization
LHP Collaboration, S. Basak, R. Edwards +7
We have computed correlation functions for nucleons and extracted the masses for positive- and negative-parities. Use of group theory plays an important role in obtaining sources t…
Baryonic Operators for Lattice Simulations
LHP Collaboration, R. Edwards, R. Fiebig +6
The construction of baryonic operators for determining the N* excitation spectrum is discussed. The operators are designed with one eye towards maximizing overlaps with the low-lyi…
Insight into nucleon structure from generalized parton distributions
LHPC Collaboration, SESAM Collaboration, J. W. Negele +11
The lowest three moments of generalized parton distributions are calculated in full QCD and provide new insight into the behavior of nucleon electromagnetic form factors, the origi…
Moments of nucleon spin-dependent generalized parton distributions
W. Schroers, R. C. Brower, P. Dreher +10
We present a lattice measurement of the first two moments of the spin-dependent GPD H-tilde(x,xi,t). From these we obtain the axial coupling constant and the second moment of the s…
