Dynamical Mass Generation in QED: Miransky scaling and Schrödinger-like infinite well and barrier potentials supporting a bound state
Juan D. García-Muñoz, A. Alfaro, L. X. Gutiérrez-Guerrero +1
In this study, we revisit the Schwinger-Dyson equation for the electron propagator in QED in three and four space-time dimensions. Our analysis addresses the non-perturbative pheno…

First Radial Excitations of Baryons in a Contact Interaction: Mass Spectrum
L. X. Gutiérrez-Guerrero, Alfredo Raya, L. Albino +1
We compute masses of twenty positive parity first radial excitations of spin- and baryons composed of u,d,s,c and b quarks in a quark-diquark picture within a contact in…
