Flavoured Warped Axion
Quentin Bonnefoy, Peter Cox, Emilian Dudas +2
We consider a 5D extension of the DFSZ axion model that addresses both the axion quality and fermion mass hierarchy problems, and predicts flavour-dependent, off-diagonal axion-fer…
The Swampland at Large Number of Space-Time Dimensions
Quentin Bonnefoy, Luca Ciambelli, Dieter Lust +1
We discuss some aspects of swampland constraints - especially the swampland distance conjecture - in a large number of space-time dimensions . We analyze Kaluza-Klein (KK) state…
Comments on gauge anomalies at dimension-six in the Standard Model Effective Field Theory
Quentin Bonnefoy, Luca Di Luzio, Christophe Grojean +2
We study whether higher-dimensional operators in effective field theories, in particular in the Standard Model Effective Field Theory (SMEFT), can source gauge anomalies via the mo…
Positivity bounds on Minimal Flavor Violation
Quentin Bonnefoy, Emanuele Gendy, Christophe Grojean
From general analyticity and unitarity requirements on the UV theory, positivity bounds on the Wilson coefficients of the dimension-8 operators composed of 4 fermions and two deriv…
The Anomalous Case of Axion EFTs and Massive Chiral Gauge Fields
Quentin Bonnefoy, Luca Di Luzio, Christophe Grojean +2
We study axion effective field theories (EFTs), with a focus on axion couplings to massive chiral gauge fields. We investigate the EFT interactions that participate in processes wi…
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…
