The as the dressed meson in a coupled-channels calculation
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
The recent discovery of the meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spect…
Accessing the pion 3D structure at US and China Electron-Ion Colliders
J. M. Morgado Chávez, V. Bertone, F. De Soto +5
We present in this letter the first systematic feasibility study of accessing generalised parton distributions of the pion at an electron-ion collider through deeply virtual Compto…
Pion GPDs: A path toward phenomenology
José Manuel Morgado Chavez, Valerio Bertone, Feliciano De Soto Borrero +5
We introduce a new family of Generalised Parton Distribution models able to fulfil by construction all the theoretical properties imposed by QCD. These models are built on standard…
Hidden-charm tetraquarks with strangeness in the chiral quark model
Gang Yang, Jialun Ping, Jorge Segovia
The hidden-charm tetraquarks with strangeness, , in , and are systematically investigated in the framework of real- and complex-s…
The structures in a constituent quark model coupled-channels calculation
Pablo G. Ortega, Jorge Segovia, Francisco Fernandez
The and are two bottomonium-like structures discovered in the , and invariant mass spectra, where…
The bosonic algebraic approach applied to the tetraquarks
A. J. Majarshin, Yan-An Luo, Feng Pan +1
The exact eigenenergies of the , , and tetraquarks are calculated within the extended tra…
Line shape and the experimental determination of the branching fraction
Jorge Segovia, Jaume Tarrús Castellà
We study the photon spectrum line-shape of the decay process in a nonrelativistic effective field theory (EFT) framework of quantum chromodynamics (QCD). We tak…
The structure of the X(3872) as explained by a Diffusion Monte Carlo calculation
M. C. Gordillo, F. De Soto, J. Segovia
Two decades after its unexpected discovery, the properties of the exotic resonance are still under intense scrutiny. In particular, there are doubts about its nature as a…
Exotic resonances of fully-heavy tetraquarks in a lattice-QCD insipired quark model
Gang Yang, Jialun Ping, Jorge Segovia
Fully-heavy tetraquark states, i.e. , , (), , , and ,…
Nucleon axial-vector and pseudoscalar form factors, and PCAC relations
Chen Chen, Christian S. Fischer, Craig D. Roberts +1
We use a continuum quark+diquark approach to the nucleon bound-state problem in relativistic quantum field theory to deliver parameter-free predictions for the nucleon axial and in…
Masses of positive- and negative-parity hadron ground-states, including those with heavy quarks
Pei-Lin Yin, Zhu-Fang Cui, Craig D. Roberts +1
A symmetry-preserving treatment of a vectorvector contact interaction is used to compute spectra of ground-state mesons, their partner diqu…
Revealing the structure of light pseudoscalar mesons at the Electron-Ion Collider
John Arrington, Carlos Ayerbe Gayoso, Patrick C Barry +29
How the bulk of the Universe's visible mass emerges and how it is manifest in the existence and properties of hadrons are profound questions that probe into the heart of strongly i…
The tetraquarks in the chiral quark model
Gang Yang, Jialun Ping, Jorge Segovia
The low-lying tetraquark states with , and , and in the isoscalar and isovector sectors, are systematically investigat…
