Light-meson masses in an unquenched quark model
Xiaoyun Chen, Jialun Ping, Craig D. Roberts +1
We perform a coupled-channels calculation of the masses of light mesons with the quantum numbers , , by including and components in a…
Parton distribution amplitudes: revealing diquarks in the proton and Roper resonance
Cedric Mezrag, Jorge Segovia, Lei Chang +1
We present the first quantum field theory calculation of the pointwise behaviour of the leading-twist parton distribution amplitudes (PDAs) of the proton and its lightest radial ex…
Structure of the nucleon's low-lying excitations
Chen Chen, Bruno El-Bennich, Craig D. Roberts +3
A continuum approach to the three valence-quark bound-state problem in quantum field theory is used to perform a comparative study of the four lightest bary…
Parity partners in the baryon resonance spectrum
Ya Lu, Chen Chen, Craig D. Roberts +3
We describe a calculation of the spectrum of flavour-SU(3) octet and decuplet baryons, their parity partners, and the radial excitations of these systems, made using a symmetry-pre…
Exposing strangeness: projections for kaon electromagnetic form factors
Fei Gao, Lei Chang, Yu-Xin Liu +2
A continuum approach to the kaon and pion bound-state problems is used to reveal their electromagnetic structure. For both systems, when used with parton distribution amplitudes ap…
Off-shell persistence of composite pions and kaons
Si-Xue Qin, Chen Chen, Cedric Mezrag +1
In order for a Sullivan-like process to provide reliable access to a meson target as becomes spacelike, the pole associated with that meson should remain the dominant feature o…
