Effective charge from lattice QCD
Zhu-Fang Cui, Jin-Li Zhang, Daniele Binosi +7
Using lattice configurations for quantum chromodynamics (QCD) generated with three domain-wall fermions at a physical pion mass, we obtain a parameter-free prediction of QCD's reno…
Excited light baryons from quark-gluon-level calculations
J. Segovia, C. Chen, Z. -F. Cui +2
The task of mapping and explaining the spectrum of baryons and the structure of these states in terms of quarks and gluons is a longstanding challenge in hadron physics, which is l…
Doubly-heavy tetraquarks
Gang Yang, Jialun Ping, Jorge Segovia
In the framework of the chiral quark model along with complex scaling range, we perform a dynamical study on the low-lying -wave doubly-heavy tetraquark states ($QQ\bar{q}\bar{q…
The charged and structures in a constituent quark model approach
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
The nature of the recently discovered and structures is intriguing. Their charge forces its minimal quark content to be (where and $q=\{u,…
Form factors for the Nucleon-to-Roper electromagnetic transition at large-
José Rodríguez-Quintero, Daniele Binosi, Chen Chen +3
We report on a recent calculation of all Roper-related electromagnetic transtions form factors, covering the range of energies that next-to-come planned experiments are expected to…
Spin Structure of heavy-quark hybrids
Jaume Tarrús Castellà
Exotic quarkonia are candidates to new types of hadrons including four quarks or gluonic degrees of freedom as constituents, the latter being a unique feature of QCD. We review rec…
QCD spin effects in the heavy hybrid potentials and spectra
Nora Brambilla, Wai Kin Lai, Jorge Segovia +1
The spin-dependent operators for heavy quarkonium hybrids have been recently obtained in a nonrelativistic effective field theory approach up to next-to-leading order in the heavy-…
Pion and Kaon Structure at the Electron-Ion Collider
Arlene C. Aguilar, Zafir Ahmed, Christine Aidala +48
Understanding the origin and dynamics of hadron structure and in turn that of atomic nuclei is a central goal of nuclear physics. This challenge entails the questions of how does t…
Structure of the nucleon and its first radial excitation
Jorge Segovia
A Poincaré-covariant continuum approach to the three valence-quark bound-state problem in quantum field theory is used to perform a detailed analysis of the nucleon's ground and fi…
Transition form factors: ,
Ya Lu, Chen Chen, Zhu-Fang Cui +4
Electroproduction form factors describing the transitions are computed using a fully-dynamical diquark-quark approximation to the Poincaré-covar…
Triply-heavy baryons in a constituent quark model
Gang Yang, Jialun Ping, Pablo G. Ortega +1
A constituent quark model, which has recently been successfully applied to the study of heavy quarkonium properties such as its spectrum but also a diverse array of observables rel…
Masses of ground-state mesons and baryons, including those with heavy quarks
Pei-Lin Yin, Chen Chen, Gastao Krein +3
Using a confining, symmetry-preserving regularisation of a vectorvector contact interaction, we compute the spectra of ground-state pseudoscalar and vector meso…
Spectrum and structure of octet and decuplet baryons and their positive-parity excitations
Chen Chen, Gastao Krein, Craig D. Roberts +2
A continuum approach to the three valence-quark bound-state problem in quantum field theory, employing parametrisations of the necessary kernel elements, is used to compute the spe…
