Origin of the Proton Mass
Craig D. Roberts
Atomic nuclei lie at the core of everything visible; and at the first level of approximation, their atomic weights are simply the sum of the masses of all the neutrons and protons…
Emergence of Hadron Mass and Structure
Minghui Ding, Craig D. Roberts, Sebastian M. Schmidt
Visible matter is characterised by a single mass scale; namely, the proton mass. The proton's existence and structure are supposed to be described by quantum chromodynamics (QCD);…
Contact interaction analysis of octet baryon axialvector and pseudoscalar form factors
Peng Cheng, Fernando E. Serna, Zhao-Qian Yao +3
Octet baryon axial, induced pseudoscalar, and pseudoscalar form factors are computed using a symmetry-preserving treatment of a vectorvector contact interaction (SCI),…
Bethe-Salpeter kernel and properties of strange-quark mesons
Zhen-Ni Xu, Zhao-Qian Yao, Si-Xue Qin +2
Focusing on the continuum meson bound-state problem, a novel method is used to calculate closed-form Bethe-Salpeter kernels that are symmetry consistent with any reasonable gluon-q…
Nucleon axial form factor at large momentum transfers
Chen Chen, Craig D. Roberts
Using a Poincaré-covariant quark+diquark Faddeev equation and related symmetry-preserving weak interaction current, we deliver parameter-free predictions for the nucleon axialvecto…
Heavy + heavy and heavy + light pseudoscalar to vector semileptonic transitions
Hui-Yu Xing, Zhen-Ni Xu, Zhu-Fang Cui +2
Using a symmetry-preserving regularisation of a vectorvector contact interaction (SCI), we complete a systematic treatment of twelve semileptonic transitions with vector me…
Fresh look at experimental evidence for odderon exchange
Zhu-Fang Cui, Daniele Binosi, Craig D. Roberts +2
Theory suggests that in high-energy elastic hadron+hadron scattering, -channel exchange of a family of colourless crossing-odd states -- the odderon -- may generate differences…
Symplectic Effective Field Theory for Nuclear Structure Studies
D. Kekejian, J. P. Draayer, V. I. Mokeev +1
A Symplectic Effective Field Theory that unveils the observed emergence of symplectic symmetry in atomic nuclei is advanced. Specifically, starting from a simple extension of the h…
Hadron and light nucleus radii from electron scattering
Zhu-Fang Cui, Daniele Binosi, Craig D. Roberts +1
Conceptually, radii are amongst the simplest Poincaré-invariant properties that can be associated with hadrons and light nuclei. Accurate values of these quantities are necessary s…
Composition of low-lying -baryons
Langtian Liu, Chen Chen, Ya Lu +2
A Poincaré-covariant quark+diquark Faddeev equation is used to develop insights into the structure of the four lightest baryon multiplets. W…
Proton and pion distribution functions in counterpoint
Ya Lu, Lei Chang, Khépani Raya +2
Working with proton and pion valence distribution functions (DFs) determined consistently at the same, unique hadron scale and exploiting the possibility that there is an effective…
Parton distributions of light quarks and antiquarks in the proton
Lei Chang, Fei Gao, Craig D. Roberts
An algebraic Ansatz for the proton's Poincaré-covariant wave function, which includes both scalar and pseudovector diquark correlations, is used to calculate proton valence, sea, a…
