Type IIB at eight derivatives: Five-Point Axio-Dilaton Couplings
James Liu, Ruben Minasian, Raffaele Savelli +1
We study the Type IIB eight-derivative effective Lagrangian beyond the quartic level, focusing on interactions involving gravitons and axio-dilatons. We show how to translate five-…
Duality-Symmetry Enhancement in Maxwell Theory
Shani Meynet, Daniele Migliorati, Raffaele Savelli +1
Free Maxwell theory on general four-manifolds may, under certain conditions on the background geometry, exhibit holomorphic factorization in its partition function. We show that wh…
Systematics of the Expansion in F-Theory
Michele Cicoli, Fernando Quevedo, Raffaele Savelli +2
Extracting reliable low-energy information from string compactifications notoriously requires a detailed understanding of the UV sensitivity of the corresponding effective field th…
A vanishing theorem for T-branes
Fernando Marchesano, Ruxandra Moraru, Raffaele Savelli
We consider regular polystable Higgs pairs on compact complex manifolds. We show that a non-trivial Higgs field restricts the Ricci…
The Geometry of SUSY Enhancement
Federico Carta, Simone Giacomelli, Hirotaka Hayashi +1
We provide a precise geometric picture that demystifies the phenomenon of supersymmetry enhancement along certain RG flows of four-dimensional field theories, recently discovered b…
The two faces of T-branes
Iosif Bena, Johan Blåbäck, Raffaele Savelli +1
We establish a brane-brane duality connecting T-branes to collections of ordinary D-branes. T-branes are intrinsically non-Abelian brane configurations with worldvolume flux, where…
