String Defects, Supersymmetry and the Swampland
Carlo Angelantonj, Quentin Bonnefoy, Cezar Condeescu +1
Recently, Kim, Shiu and Vafa proposed general consistency conditions for six dimensional supergravity theories with minimal supersymmetry coming from couplings to strings. We test…
Weak gravity (and other conjectures) with broken supersymmetry
Quentin Bonnefoy, Emilian Dudas, Severin Lüst
We study the weak gravity conjecture in non-supersymmetric string theory setups. Precisely, those are type I string theory with supersymmetry broken à la Scherk-Schwarz and open st…
Infinite Black Hole Entropies at Infinite Distances and Tower of States
Quentin Bonnefoy, Luca Ciambelli, Dieter Lust +1
The aim of this paper is to elucidate a close connection between the black hole area law and the infinite distance conjecture in the context of the swampland. We consider families…
Chiral Froggatt-Nielsen models, gauge anomalies and flavourful axions
Q. Bonnefoy, E. Dudas, S. Pokorski
We study UV-complete Froggatt-Nielsen-like models for the generation of mass and mixing hierarchies, assuming that the integrated heavy fields are chiral with respect to an abelian…
BPS solutions for generalised Wess-Zumino models and their applications
Steven Abel, Quentin Bonnefoy, Debtosh Chowdhury
We present BPS solutions to a general class of Wess-Zumino models which extend previous results in the literature. We discuss their relation to amplitudes on threshold, and their a…
Axions and anomalous 's
Quentin Bonnefoy, Emilian Dudas
Inspired by recent studies of high-scale decay constant or flavorful QCD axions, we review and clarify their existence in effective string models with anomalous gauge groups…
