Quark mass functions in Minkowski space
Elmar P. Biernat, Franz Gross, M. T. Peña +1
Using the Covariant Spectator Theory (CST), we calculate the dressed quark mass function and wave-function renormalization for the five quark flavors from up/down to bottom in both…
Five-body systems with Bethe-Salpeter equations
Gernot Eichmann, M. T. Peña, Raul D. Torres
We extend the Bethe-Salpeter formalism to systems made of five valence particles. Restricting ourselves to two-body interactions, we derive the subtraction terms necessary to preve…
Electromagnetic Transition Form Factors of Baryon Resonances
G. Ramalho, M. T. Peña
Recent experimental and theoretical advancements have led to significant progress in our understanding of the electromagnetic structure of nucleons (), nucleon excitations ($N^\…
Heavy baryon spectroscopy in a quark-diquark approach
A. Torcato, A. Arriaga, G. Eichmann +1
We report progress on calculations of the heavy-light baryons and and their excitations with using functional methods. We employ a covariant quark-diquark…
Covariant model for the Dalitz decay of the resonance
G. Ramalho, M. T. Peña
We develop a covariant model for the transition in the timelike kinematical region, the region where the square momentum transfer is positive. Our star…
Hyperon electromagnetic timelike elastic form factors at large
G. Ramalho, M. T. Peña, K. Tsushima
We present estimates of the hyperon elastic form factors for the baryon octet and the baryon for large four-momentum transfer squared, , in the timelike region ()…
