Light-front Ward-Takahashi Identity for Two-Fermion Systems
J. A. O. Marinho, T. Frederico, E. Pace +2
We propose a three-dimensional electromagnetic current operator within light-front dynamics that satisfies a light-front Ward-Takahashi identity for two-fermion systems. The light-…
Electromagnetic Decays of Vector Mesons in a Covariant Model
Silvia Pisano, Tobias Frederico, Emanuele Pace +1
A fully covariant model for describing the electromagnetic decay of Vector Mesons, both in light and in heavy sectors, is presented. The main ingredients of our approach are i) an…
Linear meson and baryon trajectories in AdS/QCD
Hilmar Forkel, Michael Beyer, Tobias Frederico
An approximate holographic dual of QCD is constructed and shown to reproduce the empirical linear trajectories of universal slope on which the square masses of radially and orbital…
Linear square-mass trajectories of radially and orbitally excited hadrons in holographic QCD
Hilmar Forkel, Michael Beyer, Tobias Frederico
We consider a new approach towards constructing approximate holographic duals of QCD from experimental hadron properties. This framework allows us to derive a gravity dual which re…
Timelike and spacelike hadron form factors, Fock state components and light-front dynamics
E. Pace, G. Salme`, T. Frederico +2
A unified description of spacelike and timelike hadron form factors within a light-front model was successfully applied to the pion. The model is extended to the nucleon to study t…
Kaon Eletromagnetic Form Factor in the Light-Front Formalism
Fabiano P. Pereira, J. P. B. C. de Melo, T. Frederico +1
Numerical calculations are performed and compared to the experimental data for the electromagnetic form factor of the kaon, which is extracted from both components of the electroma…
