pi- and rho-mesons, and their diquark partners, from a contact interaction
H. L. L. Roberts, A. Bashir, L. X. Gutierrez-Guerrero +2
We present a unified Dyson-Schwinger equation treatment of static and electromagnetic properties of pseudoscalar and vector mesons, and scalar and axial-vector diquark correlations…
Pion and kaon valence-quark parton distribution functions
Trang Nguyen, Adnan Bashir, Craig D. Roberts +1
A rainbow-ladder truncation of QCD's Dyson-Schwinger equations, constrained by existing applications to hadron physics, is employed to compute the valence-quark parton distribution…
Critical Number of Flavours in QED
A. Bashir, C. Calcaneo-Roldan, L. X. Gutiérrez-Guerrero +1
We demonstrate that in unquenched quantum electrodynamics (QED), chiral symmetry breaking ceases to exist above a critical number of fermion flavours . This is a necessary and…
