Weyl-Invariant Light-Like Branes and Black Hole Physics
Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov +1
We propose a new class of p-brane theories which are Weyl-conformally invariant for any p. For any odd world-volume dimension the latter describe intrinsically light-like branes, h…
Impact of Dynamical Tensions in Modified String and Brane Theories
E. I. Guendelman, A. Kaganovich, E. Nissimov +1
First we briefly outline the general construction of Dp-brane models with dynamical tensions. We then proceed to a more detailed discussion of a modified string model where the str…
Composite Vector and Tensor Gauge Fields, and Volume-Preserving Diffeomorphisms
Eduardo I. Guendelman, Emil Nissimov, Svetlana Pacheva
We describe new theories of composite vector and tensor (p-form) gauge fields made out of zero-dimensional constituent scalar fields (``primitives''). The local gauge symmetry is r…
