The Vector-Tensor Supermultiplet with Gauged Central Charge
The vector-tensor multiplet is coupled off-shell to an N = 2 vector multiplet such that its central charge transformations are realized locally. A gauged central charge is a necessary prerequisite for a coupling to supergravity and the strategy underlying our construction uses the potential for such a coupling as a guiding principle. The results for the action and transformation rules take a no...

New string models in D = 4 space-time extended by tensor central charge coordinates zmn are constructed. We use the zmn coordinates to generate string tension using a minimally extended string action linear in dz mn. It is shown that the presence of zmn lifts the light-like character of the tensionless string worldsheet and the degeneracy of its induced metric. We analyse the equations of motio...
متن کاملTensor Coordinates in Noncommutative Mechanics
A consistent classical mechanics formulation is presented in such a way that, under quantization, it gives a noncommutative quantum theory with interesting new features. The Dirac formalism for constrained Hamiltonian systems is strongly used, and the object of noncommutativity θ plays a fundamental rule as an independent quantity. The presented classical theory, as its quantum counterpart, is ...
متن کاملStrings with Discrete Target Space
We investigate the field theory of strings having as a target space an arbitrary discrete onedimensional manifold. The existence of the continuum limit is guaranteed if the target space is a Dynkin diagram of a simply laced Lie algebra or its affine extension. In this case the theory can be mapped onto the theory of strings embedded in the infinite discrete line ZZ which is the target space of ...
متن کاملF - 13288 Marseille – Cedex 9 N = 4 Supergravity with Antisymmetric Tensor in Central Charge Superspace
A concise geometrical formulation of N = 4 supergravity containing an antisymmetric tensor gauge field is given in central charge superspace: graviphotons are identified in the super–vielbein on the same footing as the vierbein and the Rarita–Schwinger fields. As a consequence of superspace soldering, Chern–Simons terms in the fieldstrength of the antisymmetric tensor arise as an intrinsic prop...
