Hadronic fluctuations and quark-antiquark asymmetry in the nucleon
H. R. Christiansen, J. Magnin
We derive the nucleon non-perturbative sea-quark distributions coming from a composite model involving quarks and hadronic degrees of freedom. The model predicts a definite structu…
Uniqueness of Bogomol'nyi equations and Born-Infeld like supersymmetric theories
H. R. Christiansen, C. Nuñez, F. A. Schaposnik
We discuss Bogomol'nyi equations for general gauge theories (depending on the two Maxwell invariants and ) coupled to Higgs scalars. By analys…
Topological contributions to fermionic correlators and nonperturbative aspects of QCD in two dimensions
Hugo Christiansen
We analyze the formation of fermionic condensates in two dimensional quantum chromodynamics for matter in the fundamental representation of the gauge group. We show that a topologi…
Self-dual vortices in a Maxwell-Chern-Simons model with non-minimal coupling
H. R. Christiansen, M. S. Cunha, J. A. Helayel-Neto +2
We find self-dual vortex solutions in a Maxwell-Chern-Simons model with anomalous magnetic moment. From a recently developed N=2-supersymmetric extension, we obtain the proper Bogo…
N=2-Maxwell-Chern-Simons model with anomalous magnetic moment coupling via dimensional reduction
H. R. Christiansen, M. S. Cunha, J. A. Helayel-Neto +2
An N=1--supersymmetric version of the Cremmer-Scherk-Kalb-Ramond model with non-minimal coupling to matter is built up both in terms of superfields and in a component-field formali…
Strange / anti-strange asymmetry in the nucleon sea
H. R. Christiansen, J. Magnin
We analyze the non-perturbative structure of the strange sea of the nucleon within a meson cloud picture. In a low approach in which the nucleon is viewed as a three valon bo…
