SUMMARY:Weak Gravity Conjecture from Unitarity and Causality\, Theory 
 Seminar (High Energy/Cosmology)\, Toshifumi Noumi\, Kobe University
DESCRIPTION:The Weak Gravity Conjecture\, motivated by string theory a
 nd 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 gr
 avity\, which provides theoretical constraints on models of inflation 
 and dark matter for example. In this talk\, I will first review the We
 ak Gravity Conjecture and its phenomenological implications. I will th
 en introduce our recent work providing its strong evidence based on un
 itarity and causality.
