Exploring the Landscape of Flux Vacua
Gianguido Dall'Agata
(CERN)
Abstract:
I will discuss some features of string theory flux vacua that have not been explored before. Inspired by the analogy with the 4-dimensional black-hole solutions, I will show that the moduli fixing by fluxes can be described by an attractor mechanism. The discussion will be mainly focussed on non-Kaeheler attracting manifolds. I will then describe the general features of the domain-wall solutions interpolating between different vacua, explaining the vacua resolution by tunnelling and the (meta)stability properties of de Sitter uplifts.

(Swansea)
Abstract:
D-branes are considered by the general particle physics
community as the arcane inventions of the initiated having no
relevance to even semi-realistic QFTs. In this seminar I want to
provide compelling evidence that the domain walls of the simplest
supersymmetric extension of QCD are D-branes for the confining string
of the theory. Conventional D-brane technology then leads to a
very intriguing result for the forces between the domain walls which
suggests some underlying but unknown magic is at work.
