Title (deu)
A Distance Conjecture for Branes

Description (deu)
This talk is part of the thematic programme on "The Landscape vs. the Swampland". The Sharpened Distance Conjecture is not, on its own, preserved under dimensional reduction. We propose its generalization, the Brane Distance Conjecture, as a necessary condition for it to be preserved under reduction. This new conjecture holds that, in any asymptotic distance Delta in the moduli space of string vacua of a D-dimensional theory, among the set of particle towers or non-particle branes with at most P<D-1 spacetime dimensions, at least one of these becomes exponentially low tension by T~exp(-alpha Delta), where alpha is at least 1/sqrt(D-P-1). I will also discuss taxonomy rules for branes that control dot products between scalar charge-to-tensions ratios (-nabla log T) of branes, as well as relationships between these vectors and the moduli-dependent species scale. Based on work with Ben Heidenreich and Tom Rudelius.
