Titre  Towards understanding the minimal weak gravity conjecture 
Résumé  The weak gravity conjecture asserts that any consistent gauge theory coupled to quantum gravity should exhibit socalled superextremal particles, i.e. states whose chargetomass ratio exceeds that of an extremal black hole. On the other hand, a stronger variant of this conjecture is the tower weak gravity conjecture, which predicts an infinite tower of superextremal states in every direction of the charge lattice of the theory under consideration. This formulation ensures that the weak gravity conjecture remains consistent under circle reduction of a given theory. However, in string theory compactifications on CalabiYau threefolds, there are instances where no tower of superextremal particle states appears to be present. To address this issue, I will discuss recent developments in our understanding of the tower weak gravity conjecture leading to the Minimal Weak Gravity Conjecture, which states that towers of superextremal particles occur if and only if they are required by consistency of the weak gravity conjecture under dimensional reduction.
