On Skyrmion semiclassical quantization in the presence of an isospin chemical potential
Thomas D. Cohen, Juan A. Ponciano, Norberto N. Scoccola
The semiclassical description of Skyrmions at small isospin chemical potential is carefully analyzed. We show that when the calculation of the energy of a nucleon is performe…
Skyrmions in the presence of isospin chemical potential
J. A. Ponciano, N. N. Scoccola
We analyze the existence of localized finite energy topological excitations on top of the perturbative pion vacuum within the Skyrme model at finite isospin chemical potential and…
Approximate solutions for the single soliton in a Skyrmion-type model with a dilaton scalar field
J. A. Ponciano, C. A. Garcia Canal
We consider the analytical properties of the single-soliton solution in a Skyrmion-type Lagrangian that incorporates the scaling properties of quantum chromodynamics (QCD) through…
Minimal left-right symmetric models and new properties at future electron-positron colliders
F. M. L. Almeida, Y. A. Coutinho, J. A. Martins Simões +4
It was recently shown that left-right symmetric models for elementary particles can be built with only two Higgs doublets. The general consequence of these models is that the left…
Neutrino mixing in a left-right model
J. A. Martins Simoes, J. Ponciano
We study the mixing among different generations of massive neutrino fields in a gauge theory which includes Majorana and Dirac mass terms in…
Approximate solutions for the skyrmion
J. A. Ponciano, L. N. Epele, H. Fanchiotti +1
We reconsider the Euler-Lagrange equation for the Skyrme model in the hedgehog ansatz and study the analytical properties of the solitonic solution. In view of the lack of a closed…
