Lattice QCD in Background Fields
William Detmold, Brian C. Tiburzi, Andre Walker-Loud
Electromagnetic properties of hadrons can be computed by lattice simulations of QCD in background fields. We demonstrate new techniques for the investigation of charged hadron prop…
Connected Parts of Decuplet Electromagnetic Properties
B. C. Tiburzi
We determine the electromagnetic properties of decuplet resonances using chiral perturbation theory at next-to-leading order. Utilizing a partially quenched charge matrix, we isola…
Time Dependence of Nucleon Correlation Functions in Chiral Perturbation Theory
B. C. Tiburzi
We consider corrections to nucleon correlation functions arising from times that are far from the asymptotic limit. For such times, the single nucleon state is contaminated by the…
Volume Effects for Pion Two-Point Functions in Constant Electric and Magnetic Fields
Brian C. Tiburzi
We compute finite volume effects relevant for lattice QCD simulations using background fields. Focusing on constant electric and magnetic fields on a periodic lattice, we determine…
Flavor Twisted Boundary Conditions, Pion Momentum, and the Pion Electromagnetic Form Factor
F. -J. Jiang, B. C. Tiburzi
We investigate the utility of partially twisted boundary conditions in lattice calculations of meson observables. For dynamical simulations, we show that the pion dispersion relati…
Electromagnetic and spin polarisabilities in lattice QCD
W. Detmold, B. C. Tiburzi, A. Walker-Loud
We discuss the extraction of the electromagnetic and spin polarisabilities of nucleons from lattice QCD. We show that the external field method can be used to measure all the elect…
