Quark-model relations among TMDs in the parton model
F. Aslan, S. Bastami, A. Mahabir +2
The covariant parton model (CPM) is a consequent application of the parton model concept to the nucleon structure. In this model, there is a choice to put quarks either in a pure-s…
Transverse Force Imaging
Fatma P. Aslan, Matthias Burkardt, Marc Schlegel
While twist-2 GPDs allow for a determination of the distribution of partons on the transverse plane, twist-3 GPDs contain quark-gluon correlations that provide information about th…
Lorentz invariance relations for twist-3 quark distributions
Fatma P. Aslan, Matthias Burkardt
We calculate twist-3 parton ditribution functions (PDFs) using cut and uncut diagrams. Uncut diagrams lead to a Dirac delta function term. No such term appears when cut diagrams ar…
Transverse Force Tomography
Fatma P. Aslan, Matthias Burkardt, Marc Schlegel
While twist-2 GPDs allow for a determination of the distribution of partons on the transverse plane, twist-3 GPDs contain quark-gluon correlations that provide information about th…
Singularities in Twist-3 Quark Distributions
Fatma Aslan, Matthias Burkardt
We find in one-loop calculations and spectator models that twist-3 GPDs exhibit discontinuities. In the forward limit these discontinuities grow into Dirac delta functions which ar…
Twist-3 GPDs in Deeply-Virtual Compton Scattering
Fatma Aslan, Matthias Burkardt, Cédric Lorcé +2
The sub-leading power of the scattering amplitude for deeply-virtual Compton scattering (DVCS) off the nucleon contains leading-twist and twist-3 generalized parton distributions (…
