Warped Supersymmetry Breaking
C. P. Burgess, P. G. Camara, S. P. de Alwis +4
We address the size of supersymmetry-breaking effects within higher-dimensional settings where the observable sector resides deep within a strongly warped region, with supersymmetr…
String Phenomenology and the Cosmological Constant
S. P. de Alwis
It is argued that classical string solutions should not be fine tuned to have a positive cosmological constant (CC) at the observed size, since even the quantum corrections from st…
The Scales of Brane Nucleation Processes
S. P. de Alwis
The scales associated with Brown-Teitelboim-Bousso-Polchinski processes of brane nucleation, which result in changes of the flux parameters and the number of D-branes, are discusse…
Transitions Between Flux Vacua
S. P. de Alwis
A dynamical description of the transitions between different backgrounds requires the existence of a background independent action which propagates the correct number of degrees of…
Potentials for Light Moduli in Supergravity and String Theory
S. P. de Alwis
This is an account of lectures that were given at TASI 2005, the Shanghai Summer School in M-theory 2005 and the Perimeter Institute. I review 1) the derivation of the potential fo…
