9 Oct 2007 | Abstract: | We discuss a deformation of the Hopf algebra of supersymmetry (SUSY)
transformations based on a special choice of twist. As usual, algebra itself
remains unchanged, but the comultiplication changes. This leads to the deformed
Leibniz rule for SUSY transformations. Superfields are elements of the algebra
of functions of the usual supercoordinates. Elements of this algebra are
multiplied by using a $star$-product which is noncommutative, hermitian and
finite when expanded in power series of the deformation parameter. Chiral
fields are no longer a subalgebra of the algebra of superfields. One possible
deformation of the Wess-Zumino action is proposed and analysed in detail.
Differently from most of the literature concerning this subject, we work in
Minkowski space-time. | Source: | arXiv, 0710.1746 | Services: | Forum | Review | PDF | Favorites |
