Affine Algebras at Infinite Distance Limits in the Heterotic String
Veronica Collazuol, Mariana Graña, Alvaro Herráez +1
We analyze the boundaries of the moduli spaces of compactifications of the heterotic string on , making particular emphasis on and its F-theory dual. We compute the OPE…
symmetry in the Heterotic String on and the Weak Gravity Conjecture
Veronica Collazuol, Mariana Graña, Alvaro Herráez
We show that compactifications of the heterotic string on a circle exhibit at the boundary of moduli space (, or equivalently the decompactification limit ) a…
IR/UV Mixing, Towers of Species and Swampland Conjectures
Alberto Castellano, Alvaro Herráez, Luis E. Ibáñez
By applying the Covariant Entropy Bound (CEB) to an EFT in a box of size one obtains that the UV and IR cut-offs of the EFT are necessarily correlated. We argue t…
The Swampland Conjectures: A bridge from Quantum Gravity to Particle Physics
Mariana Graña, Alvaro Herráez
The swampland is the set of seemingly consistent low-energy effective field theories that cannot be consistently coupled to quantum gravity. In this review we cover some of the con…
On scale separation in type II AdS flux vacua
Anamaría Font, Alvaro Herráez, Luis E. Ibáñez
We study the separation of AdS and Kaluza-Klein (KK) scales in type II 4d AdS orientifold vacua. We first address this problem in toroidal/orbifold type IIA vacua with metric fluxe…
The Swampland Distance Conjecture and Towers of Tensionless Branes
Anamaría Font, Alvaro Herráez, Luis E. Ibáñez
The Swampland Distance Conjecture states that at infinite distance in the scalar moduli space an infinite tower of particles become exponentially massless. We study this issue in t…
