SPS Journal Club: Weak Gravity and Perturbative Black Holes

Speaker: Matteo Lotito (IFT)

Venue&Time: Red Room / 12:00

Abstract:

I present a brief summary of the derivation of the Weak Gravity Conjecture within perturbative string theory, following [2403.14449], and highlight possible gaps that may hinder a fully consistent proof. I then analyze the existence and properties of the black hole solutions whose extremality bounds are compared to the string spectrum in the statement of the WGC. This analysis demonstrates that the black hole solutions we employ in our setup are reliable and do not undermine the validity of our results.
