Venue: Seminar Room A 113 (Cripps North Building, CAPT)


Title: Scale separation with strings attached


Abstract:  Empirical evidence famously indicates that we live in a universe with four extended spacetime dimensions and no "fifth forces" at low energies. Building realistic universes from string theory runs into several challenges, among which achieving both of these conditions simultaneously. This is known as the scale separation problem. I will present a novel approach to this end, concocting four-dimensional string vacua directly from the worldsheet formulation by analogy with the Banks-Zaks phenomenon in gauge theory. The resulting vacua are non-supersymmetric anti-de Sitter spacetimes with no intermediate effective description in higher dimensions. I will provide a working example in four dimensions as a proof of principle.
