We show that the strong CP problem is solved in a large class of compactifications of string theory. The Peccei-Quinn mechanism solves the strong CP problem if the CP-breaking effe…
A Cosmological Constant That is Too Small
Mehmet Demirtas, Manki Kim, Liam McAllister +2
We construct a vacuum of string theory in which the magnitude of the vacuum energy is in Planck units. Regrettably, the sign of the vacuum energy is negative, and som…
Small Cosmological Constants in String Theory
Mehmet Demirtas, Manki Kim, Liam McAllister +2
We construct supersymmetric vacua of type IIB string theory in compactifications on orientifolds of Calabi-Yau threefold hypersurfaces. We first find explicit orie…
Resolving spacetime singularities in flux compactifications & KKLT
Federico Carta, Jakob Moritz
In flux compactifications of type IIB string theory with D3 and seven-branes, the negative induced D3 charge localized on seven-branes leads to an apparently pathological profile o…
