Nucleon Parton Distribution Amplitude: A scalar diquark picture
Cédric Mezrag, Jorge Segovia, Minghui Ding +2
We report progress on the development of Perturbative Integral Representation Ansätze to compute the nucleon Faddeev Wave function, using an explicit quark-diquark picture. Our for…
Nucleon-to-Roper electromagnetic transition form factors at large-
Chen Chen, Ya Lu, Daniele Binosi +3
High-precision nucleon-resonance electroproduction data on a large kinematic domain of energy and momentum transfer have proven crucial in revealing novel features of strong intera…
Electric dipole transitions of bottomonia
Jorge Segovia, Sebastian Steinbeißer, Antonio Vairo
We compute the electric dipole transitions , with , and in a model-independent way. We use potential non-relativistic QCD (…
Heavy mesons in the Quark Model
D. R. Entem, P. G. Ortega, J. Segovia +1
Since the discovery of the , the quark model was very successful in describing the spectrum and properties of heavy mesons including only components. However since 2…
Hidden-Bottom Pentaquarks
Gang Yang, Jialun Ping, Jorge Segovia
The LHCb Collaboration has recently reported strong evidences of the existence of pentaquark states in the hidden-charm baryon sector, the so-called and …
The structures in a coupled-channels model
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
The and are two charmonium-like structures discovered in the and invariant mass spectra. Their…
The charm/bottom quark mass from heavy quarkonium at NLO
Clara Peset, Antonio Pineda, Jorge Segovia
We determine the charm and bottom quark masses using the NLO perturbative expression of the ground state (pseudoscalar) energy of the bottomonium, charmonium and systems:…
Spin structure of heavy-quark hybrids
Nora Brambilla, Wai Kin Lai, Jorge Segovia +2
A unique feature of quantum chromodynamics (QCD), the theory of strong interactions, is the possibility for gluonic degrees of freedom to participate in the construction of physica…
Valence-quark structure N* resonances from DSEs
Jorge Segovia
We present a unified Quantum Chromodynamics (QCD)-based description of elastic and transition electromagnetic form factors involving the nucleon and its resonances. We compare pred…
Nucleon viewed as a Borromean Bound-State
Jorge Segovia, Cédric Mezrag, Lei Chang +1
We explain how the emergent phenomenon of dynamical chiral symmetry breaking ensures that Poincaré covariant analyses of the three valence-quark scattering problem in continuum qua…
