Quintessence Model Building
Ph. Brax, J. Martin, A. Riazuelo
A short review of some of the aspects of quintessence model building is presented. We emphasize the role of tracking models and their possible supersymmetric origin.
Non-BPS Branes of Supersymmetric Brane Worlds
Philippe Brax, Adam Falkowski, Zygmunt Lalak
We consider five-dimensional brane worlds with N=2 gauged supergravity in the bulk coupled supersymmetrically to two boundary branes at the fixed points of a Z_2 symmetry. We analy…
On Brane Cosmology and Naked Singularities
Ph. Brax, A. C. Davis
Brane-world singularities are analysed, emphasizing the case of supergravity in singular spaces where the singularity puzzle is naturally resolved. These naked singularities are ei…
Quintessence with two energy scales
Philippe Brax, Jerome Martin, Alain Riazuelo
We study quintessence models using low energy supergravity inspired from string theory. We consider effective supergravity with two scales m_S, the string scale, and m_PL, the Plan…
Non-BPS Instability in Heterotic M-theory
Ph. Brax
We study the warped geometry of heterotic M-Theory in five dimensions where five-branes are included in the bulk. Five-branes wrapping holomorphic curves lead to BPS configurations…
Graviton Absorption by Non-BPS Branes
Ph. Brax
We consider the behaviour of neutral non-BPS branes probed by scalars and gravitons. We show that the naked singularity of the non-BPS branes is a {\it repulson} absorbing no incom…
