Open AccessOn higher-spin points and infinite distances in conformal manifolds
Distances in the conformal manifold, the space of CFTs related by marginal deformations, can be measured in terms of the Zamolodchikov metric. Part of the CFT Distance Conjecture posits that points in this man...

Open AccessTackling the SDC in AdS with CFTs
We study the Swampland Distance Conjecture for supersymmetric theories with AdS5 backgrounds and fixed radius through their ...

Open AccessInstanton corrections and Emergent Strings
We study limits of infinite distance in the moduli space of 4d N\( \mathcal{N} \) = 2 string compactifications, in which instanton effects dominate. We first consider trajectories in the hypermultiplet moduli spa...

Open AccessSuperconformal blocks for mixed 1/2-BPS correlators with SU(2) R-symmetry
For SCFTs with an SU(2) R-symmetry, we determine the superconformal blocks that contribute to the four-point correlation function of a priori distinct half-BPS superconformal primaries as an expansion in terms...

Open AccessWhen rational sections become cyclic — Gauge enhancement in F-theory via Mordell-Weil torsion
We explore novel gauge enhancements from abelian to non-simply-connected gauge groups in F-theory. To this end we consider complex structure deformations of elliptic fibrations with a Mordell-Weil group of ran...

Open AccessBackreacted axion field ranges in string theory
String theory axions are interesting candidates for fields whose potential might be controllable over super-Planckian field ranges and therefore as possible candidates for inflatons in large field inflation. A...

Open AccessOn E 8 and F-theory GUTs
We study correlations between the massless field spectra of F-theory fibrations supporting an SU(5) gauge symmetry extended by Abelian symmetries and the spectra that arise from the group E ...

Open AccessThe local Callan-Symanzik equation: structure and applications
The local Callan-Symanzik equation describes the response of a quantum field theory to local scale transformations in the presence of background sources. The consistency conditions associated with this anomalo...
