Contact-interaction Faddeev equation and, inter alia, proton tensor charges
Shu-Sheng Xu, Chen Chen, Ian C. Cloet +3
A confining, symmetry-preserving, Dyson-Schwinger equation treatment of a vector-vector contact interaction is used to formulate Faddeev equations for the nucleon and Delta-baryon…
Strong diquark correlations inside the proton
Jorge Segovia
Quantum Chromodynamics is thought to be the relativistic quantum field theory that describes the strong interaction of the Standard Model. This interaction produces mesons but it i…
The role of spin-flipping terms in hadronic transitions of
Jorge Segovia, Francisco Fernandez, David R. Entem
Recent experimental data on the and processes seem to contradict the naive expectation that hadronic transitions with spin-flipping terms sho…
Understanding the nucleon as a Borromean bound-state
Jorge Segovia, Craig D. Roberts, Sebastian M. Schmidt
Analyses of the three valence-quark bound-state problem in relativistic quantum field theory predict that the nucleon may be understood primarily as a Borromean bound-state, in whi…
Completing the picture of the Roper resonance
Jorge Segovia, Bruno El-Bennich, Eduardo Rojas +4
We employ a continuum approach to the three valence-quark bound-state problem in relativistic quantum field theory to predict a range of properties of the proton's radial excitatio…
Charmed-strange Meson Spectrum: Old and New Problems
Jorge Segovia, David R. Entem, Francisco Fernandez
The LHCb Collaboration has recently reported the observation for the first time of a spin- resonance in the heavy quark sector. They have shown that the struc…
Puzzles in quarkonium hadronic transitions with two pion emission
F. Fernandez, J. Segovia, P. G. Ortega +1
The anomalously large rates of some hadronic transitions from quarkonium are studied using QCD multipole expansion (QCDME) in the framework of a constituent quark model which has b…
