The Hidden Symmetries of Yang-Mills Theory in (3+1)-dimensions
L. A. Ferreira, H. Malavazzi
We show that classical, non-supersymmetric Yang-Mills theories coupled to spin-1/2 and spin-0 elementary matter fields, in (3+1)-dimensional Minkowski space-time, possess exact str…

gauged non-topological solitons in the 3+1 dimensional sigma-model
Luiz A. Ferreira, Aliaksei Mikhaliuk, Yakov Shnir
We present and study new non-topological soliton solutions in the gauged non-linear sigma model with a symmetry breaking potential in 3+1 dimensional flat space-time.…
