Towards the Non-Perturbative Completion of 4d N=1 Effective Theories of Gravity
Gonzalo F. Casas, Max Wiesner
We show that four-dimensional effective theories of gravity obtained from string compactifications require a non-perturbative completion, as additional light states…
Moduli Self-Fixing
Gonzalo F. Casas, Luis E. Ibáñez
In Quantum Gravity (QG), large moduli values lead to towers of exponentially light states, making the QG cut-off field-dependent. In 4D supersymmetric (SUSY) theories, this cut-off…
On small Dirac Neutrino Masses in String Theory
Gonzalo F. Casas, Luis E. Ibáñez, Fernando Marchesano
We study how tiny Dirac neutrino masses consistent with experimental constraints can arise in string theory SM-like vacua. We use as a laboratory 4d type IIA Calabi--Y…
Modular Invariant Starobinsky Inflation and the Species Scale
Gonzalo F. Casas, Luis E. Ibáñez
Potentials in cosmological inflation often involve scalars with trans-Planckian ranges. As a result, towers of states become massless and their presence pushes the fundamental scal…
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…
Torsion in cohomology and dimensional reduction
Gonzalo F. Casas, Fernando Marchesano, Matteo Zatti
Conventional wisdom dictates that factors in the integral cohomology group of a compact manifold cannot be computed via smooth -forms…
