Five-Dimensional QED, Muon Pair Production and Correction to the Coulomb Potential
J. R. Nascimento, C. A de S. Pires, R. F. Ribeiro
We consider QED in five dimensions in a configuration where matter is localized on a 3-brane while foton propagates in the bulk. The idea is to investigate the effects of the Kaluz…
Supergravity brane worlds and tachyon potentials
D. Bazeia, F. A. Brito, J. R. Nascimento
We study massless and massive graviton modes that bind on thick branes which are supergravity domain walls solutions in -dimensional supergravity theories where only the supergr…
Issues of duality on non-commutative manifolds: the {\it non-equivalence} between self-dual and topologically massive models
T. Mariz, R. Menezes, J. R. S. Nascimento +2
We study issues of duality and dual equivalence in non-commutative manifolds. In particular the question of dual equivalence for the actions of the non-commutative extensions of th…
On the dual equivalence of the self-dual and topologically massive p-form models
R. Menezes, J. R. S. Nascimento, R. F. Ribeiro +1
We study the duality symmetry in p-form models containing a generalized term in spacetime manifolds of arbitrary dimensions. The equivalence between the $B_q\we…
Noncommutative massive Thirring model in three-dimensional spacetime
F. A. Brito, T. Mariz, J. R. S. Nascimento +1
We evaluate the noncommutative Chern-Simons action induced by fermions interacting with an Abelian gauge field in a noncommutative massive Thirring model in (2+1)-dimensional space…
Lorentz and CPT symmetries in commutative and noncommutative spacetime
D. Bazeia, T. Mariz, J. R. Nascimento +2
We investigate the fermionic sector of a given theory, in which massive and charged Dirac fermions interact with an Abelian gauge field, including a non standard contribution that…
