Noncommutative fields in curved space
J. Barcelos-Neto
We consider a noncommutative theory developed in a curved background. We show that the Moyal product has to be conveniently modified and, consequently, some of its old properties a…
Partially embedding of the quantum mechanical analog of the nonlinear sigma model
R. Amorim, J. Barcelos-Neto, C. Wotzasek
We consider the quantum mechanical analog of the nonlinear sigma model. There are difficulties to completely embed this theory by directly using the Batalin, Fradkin, Fradkina, and…
Extended supersymmetry in D=1+1
R. Amorim, J. Barcelos-Neto
We extend superspace by introducing an antisymmetric tensorial coordinate. The resulting theory presents a supersymmetry with central charge. After integrating over the tensorial c…
Field-antifield formalism in a non-Abelian theory with one and two form gauge fields coupled in a topological way
R. Amorim, J. Barcelos-Neto
We make a systematic development of the non-Abelian formulation of two-form gauge fields with topological coupling with the Yang-Mills one-form connection. An analysis of the gauge…
Spontaneous compactification of D=5 two-form gauge fields and the obtainment of Maxwell and Yang-Mills theories
J. Barcelos-Neto
We show that the spontaneous compactification of the Abelian and non-Abelian two-form gauge field theories from to leads to the same theories plus the Maxwell and Y…
Mass generation for gauge fields in the Salam-Weinberg theory without Higgs
J. Barcelos-Neto, S. Rabello
We consider the Salam-Weinberg theory by introducing tensor gauge fields. When these fields are coupled in a topological way with the vector ones, the resulting system constitutes…
