Potential and mass-matrix in gauged N=4 supergravity
M. de Roo, S. Panda, M. Trigiante +1
We discuss the potential and mass-matrix of gauged N=4 matter coupled supergravity for the case of six matter multiplets, extending previous work by considering the dependence on a…
Non-BPS Branes in a Type I Orbifold
E. Eyras, S. Panda
We analyse the spectrum of non-BPS branes in the type I theory on the orbifold . We present a detailed analysis of the action of the worldsheet parity on the di…
The Spacetime Life of a Non-BPS D-particle
Eduardo Eyras, Sudhakar Panda
We investigate the classical geometry generated by a stable non-BPS D-particle. We consider the boundary state of a stable non-BPS D-particle in the covariant formalism in the type…
Intersecting Branes in Matrix Theory
M. de Roo, S. Panda, J. P. van der Schaar
We construct BPS states in the matrix description of M-theory. Starting from a set of basic M-theory branes, we study pair intersections which preserve supersymmetry. The fractions…
Four-dimensional High-Branes as Intersecting D-Branes
E. Bergshoeff, M. de Roo, S. Panda
We show that a class of extremal four-dimensional supersymmetric ``high-branes'', i.e. string and domain wall solutions, can be interpreted as intersections of four ten-dimensional…
A BRST Analysis of -symmetries
E. Bergshoeff, H. J. Boonstra, S. Panda +1
We perform a classical BRST analysis of the symmetries corresponding to a generic -algebra. An essential feature of our method is that we write the -algebra in a special…
