The Boer-Mulders Function: Models and Universality
Brian Hannafious, Matthias Burkardt
The sign of the Boer-Mulders function is related to the sign of the GPD through the mechanism of chromodynamic lensing. Model calculations of the sign of $\…
Hadron Tomography
Matthias Burkardt
Generalized parton distributions describe the distribution of partons in the transverse plane. For transversely polarized quarks and/or nucleons, these impact parameter dependent p…
Hadron Tomography
Matthias Burkardt
Generalized parton distributions can be used to obtain information about the dependence of parton distributions on the impact parameter. Potential consequences for T-odd single-spi…
B-Mesons on the Transverse Lattice
M. Burkardt, S. K. Seal
We present results from a first study of -mesons that is based on a transverse lattice formulation of light-front QCD. The shape of the Isgur-Wise form factor is in very good ag…
A Study of Light Mesons on the Transverse Lattice
M. Burkardt, S. K. Seal
We present results from a study of light meson spectra and structure obtained within the framework of light-front QCD formulated on a transverse lattice. We discuss how imposing Lo…
Wilson Fermions on a Transverse Lattice
M. Burkardt, H. El-Khozondar
In the light-front formulation of field theory, it is possible to write down a chirally invariant mass term. It thus appears as if one could solve the species doubling problem on a…
An Estimate of Charge Symmetry Breaking in Nuclear Deep Inelastic Scattering
R. M. Davidson, M. Burkardt
We estimate the magnitude of charge symmetry breaking effects in deep inelastic scattering from nuclei. The resulting contribution to systematic uncertainties in hadronic determina…
A 3+1 Dimensional Light-Front Model with Spontaneous Breaking of Chiral Symmetry
M. Burkardt, H. El-Khozondar
We investigate a 3+1 dimensional toy model that exhibits spontaneous breakdown of chiral symmetry, both in a light-front (LF) Hamiltonian and in a Euclidean Schwinger-Dyson (SD) fo…
Trivial Vacua, High Orders in Perturbation Theory and Nontrivial Condensates
M. Burkardt
In the limit of an infinite number of colors, an analytic expression for the quark condensate in is derived as a function of the quark mass and the gauge coupling const…
On the Possible Violation of Sum Rules for Higher-Twist Parton Distributions
Matthias Burkardt
Precise measurements of polarized electro-production and Drell-Yan in the deep inelastic limit will soon provide first information on the higher twist parton distributions …
Polarized Fragmentation Functions from
M. Burkardt, R. L. Jaffe
Measurement of the helicity asymmetric cross section for semi-inclusive production of -hyperons in annihilation near the resonance allows a complete determination…
