Minimal Weak Gravity Conjecture and gauge duality in M-theory on K3 ×T2

Key Points

M-theory exhibits towers of superextremal states in weak and strong coupling limits, confirming the minimal weak gravity conjecture.
The study of Calabi-Yau threefolds translates between weak and strong gauge couplings, exploring non-perturbative effects.
BPS states provide important insights into the nature of effective field theory in this context, validating the conjecture.
The correspondence between curves in fiber and base allows probing of complex gauge theoretical scenarios.

Abstract

Abstract The minimal Weak Gravity Conjecture (WGC) predicts the emergence of towers of superextremal states in both weak and strong coupling limits. In this work, we study M-theory compactified on a special class of Calabi-Yau threefolds to construct a 5D effective field theory (EFT) that accommodates both weak and strong gauge coupling limits. Building on a classification of fiber structures of Calabi-Yau threefolds with finite volume, we establish a correspondence between curves in the fiber and the base, which relates weak and strong gauge couplings. This allows us to probe non-perturbative effects by treating strong couplings through their weakly counterparts. We use this result and properties of Bogomol'nyi--Prasad--Sommerfield (BPS) states to demonstrate that M-theory on such Calabi-Yau threefold exhibits towers of superextremal BPS states in the aforementioned extreme limits as expected by the minimal WGC.
