Supersymmetry and R-symmetry breaking in models with non-canonical Kahler potential
L. G. Aldrovandi, D. Marques
We analyze several aspects of R-symmetry and supersymmetry breaking in generalized O'Raifeartaigh models with non-canonical Kahler potential. Some conditions on the Kahler potentia…
Strings in Yang-Mills-Higgs theory coupled to gravity
L. G. Aldrovandi
Non-Abelian strings for an Einstein-Yang-Mills-Higgs theory are explicitly constructed. We consider N_f Higgs fields in the fundamental representation of the U(1)xSU(N_c) gauge gro…
Non-Abelian vortices in Chern-Simons theories and their induced effective theory
L. G. Aldrovandi, F. A. Schaposnik
Non-Abelian vortices for a supersymmetric {\cal N}=2 Chern-Simons-Higgs theory are explicitly constructed. We introduce N Higgs fields in the fundamental representation of the U(N)…
Quantum Mechanics in Non(Anti)Commutative Superspace
L. G. Aldrovandi, F. A. Schaposnik
We consider non(anti)commutative (NAC) deformations of d=1 N=2 superspace. We find that, in the chiral base, the deformation preserves only a half of the original (linearly realize…
A coordinate-dependent superspace deformation from string theory
L. G. Aldrovandi, F. A. Schaposnik, G. A. Silva
Starting from a type II superstring model defined on in a linear graviphoton background, we derive a coordinate dependent -deformed , su…
Non(anti)commutative superspace with coordinate-dependent deformation
L. G. Aldrovandi, F. A. Schaposnik, G. A. Silva
We consider non(anti)commutative superspace with coordinate dependent deformation parameters . We show that a chiral supersymmetry can be defined and that ch…
