Weak Gravity Conjecture from Unitarity and Causality

アブストラクト：
The Weak Gravity Conjecture, motivated by string theory and black hole
thought experiments, states that gravity is the weakest force. In
particular, it claims that there exist theoretical bounds on the
charge-to-mass ratio and the axion decay constant in quantum gravity,
which provides theoretical constraints on models of inflation and dark
matter for example. In this talk, I will first review the Weak Gravity
Conjecture and its phenomenological implications. I will then
introduce our recent work providing its strong evidence based on
unitarity and causality.
