Aharonov--Casher effect from a supersymmetric N=1 D=4 model with Kalb--Ramond Lorentz-violating background: a SUSY-preserving mechanism via the Fayet--Iliopoulos term
L. A. S. Nunes, C. A. S. Almeida
The Aharonov--Casher (AC) effect describes the geometric phase acquired by a neutral particle carrying a magnetic dipole moment moving in an external electric field. In supersymmet…

Kalb-Ramond Topological Term in Majorana Superspace and Kaluza-Klein Spectrum Deformation in Five Dimensions
L. A. S. Nunes, C. A. S. Almeida
We construct an intrinsic , superspace whose Grassmann coordinate is a five-dimensional Dirac spinor split into two Majorana spinors, , and use it to analy…
