Gravity Decoupling and Axionic Shift Symmetries
Christian Aoufia, Gonzalo F. Casas, Fernando Marchesano
We analyse the rôle of approximate axionic shift symmetries in gravity-decoupling limits arising in type II Calabi-Yau compactifications. Associated with each shift symmetry there…
F-theory flux vacua at large complex structure
Fernando Marchesano, David Prieto, Max Wiesner
We compute the flux-induced F-term potential in 4d F-theory compactifications at large complex structure. In this regime, each complex structure field splits as an axionic field pl…
Curvature divergences in 5d supergravity
Alejandro Blanco, Fernando Marchesano, Luca Melotti
We study the scalar curvature of the vector moduli space of 5d supergravities, obtained by compactifying M-theory on a Calabi--Yau three-fold. We find that …
Curvature divergences and gravity decoupling in Calabi--Yau rigid limits
Alberto Castellano, Fernando Marchesano, Lorenzo Paoloni
Four-dimensional supergravity theories become rigid in gravity-decoupling limits. We study this effect for type II string compactifications on general Calabi--Yau m…
The Moduli Space Curvature and the Weak Gravity Conjecture
Alberto Castellano, Fernando Marchesano, Luca Melotti +1
We unveil a remarkable interplay between rigid field theories (RFTs), charge-to-mass ratios and scalar curvature divergences in the vector multiplet mod…
Yukawa Couplings at Infinite Distance and Swampland Towers in Chiral Theories
Gonzalo F. Casas, Luis E. Ibáñez, Fernando Marchesano
We study limits of vanishing Yukawa couplings of 4d chiral matter fields in Quantum Gravity, using as a laboratory type IIA orientifolds with D6-branes. In these theories chiral fe…
