Nucleon tensor charges and electric dipole moments
Mario Pitschmann, Chien-Yeah Seng, Craig D. Roberts +1
A symmetry-preserving Dyson-Schwinger equation treatment of a vector-vector contact interaction is used to compute dressed-quark-core contributions to the nucleon -term and tens…
Sketching the pion's valence-quark generalised parton distribution
C. Mezrag, L. Chang, H. Moutarde +4
In order to learn effectively from measurements of generalised parton distributions (GPDs), it is desirable to compute them using a framework that can potentially connect empirical…
Nucleon and elastic and transition form factors
Jorge Segovia, Ian C. Cloet, Craig D. Roberts +1
We compute nucleon and Delta elastic and transition form factors, and compare predictions made using a framework built upon a Faddeev equation kernel and interaction vertices that…
Flavour symmetry breaking in the kaon parton distribution amplitude
Chao Shi, Lei Chang, Craig D. Roberts +3
We compute the kaon's valence-quark (twist-two parton) distribution amplitude (PDA) by projecting its Poincare'-covariant Bethe-Salpeter wave-function onto the light-front. At a sc…
Parton distribution amplitudes of light vector mesons
Fei Gao, Lei Chang, Yu-Xin Liu +2
A rainbow-ladder truncation of QCD's Dyson-Schwinger equations is used to calculate rho- and phi-meson valence-quark (twist-two parton) distribution amplitudes (PDAs) via a light-f…
Ward-Green-Takahashi identities and the axial-vector vertex
Si-Xue Qin, Craig D. Roberts, Sebastian M. Schmidt
The colour-singlet axial-vector vertex plays a pivotal role in understanding dynamical chiral symmetry breaking and numerous hadronic weak interactions, yet scant model-independent…
