Distribution amplitudes of light-quark mesons from lattice QCD
Jorge Segovia, Lei Chang, Ian C. Cloet +3
We exploit a method introduced recently to determine parton distribution amplitudes (PDAs) from minimal information in order to obtain light-quark pseudoscalar and vector meson PDA…
Constituent quark model description of charmonium phenomenology
J. Segovia, D. R. Entem, F. Fernandez +1
We review how quark models are able to describe the phenomenology of the charm meson sector. The spectroscopy and decays of charmonium and open charm mesons are described in a part…
Elastic and transition form factors of the Δ(1232)
Jorge Segovia, Chen Chen, Ian C. Cloët +3
Predictions obtained with a confining, symmetry-preserving treatment of a vector-vector contact interaction at leading-order in a widely used truncation of QCD's Dyson-Schwinger eq…
Insights into the gamma* N -> Delta transition
Jorge Segovia, Chen Chen, Craig D. Roberts +1
The γ* N -> Δ(1232) transition is a window on hadron shape deformation, the applicability of perturbative QCD at moderate momentum transfers, and the influence of nonperturbative p…
B decays into radially excited charmed mesons
J. Segovia, E. Hernández, F. Fernández +1
It has been recently argued that some longstanding problems in semileptonic B decays can be solved provided the branching ratio for the semileptonic decays…
Improved determination of Heavy Quarkonium magnetic dipole transitions in pNRQCD
Antonio Pineda, J. Segovia
We compute the magnetic dipole transitions between low lying Heavy Quarkonium states in a model independent way. We use the weak-coupling version of the effective field theory name…
