The Geometry of N=1 and N=2 Real Supersymmetric Non-Linear Sigma-Models in the Atiyah-Ward Space-Time
M. Carvalho, J. A. Helayel-Neto, M. W. de Oliveira
We analyse the structure of N=1 and N=2 supersymmetric non-linear sigma-models built up with a pair of real superfields defined in the superspace of Atiyah-Ward space-time. The geo…
Generalized Gauge Transformations and Regularized -type Abelian Vertices
Winder A. Moura-Melo, J. A. Helayel-Neto
Abelian Lagrangians containing Phi^4-type vertices are regularized by means of a suitable point-splitting scheme combined with generalized gauge transformations.. The calculation i…
Anti-symmetric Tensor Matter Fields and Non-Linear Sigma-Model
M. G. Negrao, A. Penna-Firme, J. A. Helayel-Neto
The equivalence between rank-2 anti-symmetric tensor fields, considered as gauge potentials, and torsionless non-linear -models suggests us to study the possibility of coupling…
