چکیده
In the context of string theory we argue that higher dimensional Dp-branes unwind and evaporate so that we are left with D3-branes embedded in a (9+1)-dimensional bulk. One of these D3-branes plays the rôle of our Universe. Within this picture, the evaporation of the higher dimensional Dp-branes provides the entropy of our Universe.

We derive properties of the radial evolution of scalar fields in anti-de Sitter spacetime from quantum mechanics, through a factorisation of the path integral. We describe why we anticipate application of these results to the AdS/CFT correspondence.

We describe generalizations of the manifestly E6(6) covariant formulation of five-dimensional gauged maximal supergravity with regard to the structure of the vector and tensor fields. We indicate how the group-theoretical structures that we discover seem to play a role in gauged supergravities in various space-time dimensions.

A model of gauge mediation with m 3/2 ≃ O(1) eV is considered to motivate 100 TeV colliders. Massive mediators with standard-model and supersymmetry-breaking gauge quantum numbers let low-scale dynamics induce sizable soft masses of the standard-model superpartners. We circumvent potential phenomenological difficulties that such low-scale models tend to cause.

We show how the maximally helicity violating (MHV) scattering amplitudes for gravitons can be related to current correlators and vertex operators in twistor space. This is similar to what happens in Yang-Mills theory and raises the possibility of a direct twistor-string-like construction for N = 8 supergravity.
