SUMMARY:Natural Inflation and the Weak Gravity Conjecture\, Theory Sem
 inar (High Energy/Cosmology)\, Pablo Soler Gomis\, University of Wisco
 nsin-Madison
DESCRIPTION:Axions\, enjoying an approximate shift symmetry\, are some
  of the most popular inflaton candidates in the market. Via mixing and
  alignment\, they seem to yield viable models of (natural) large field
  inflation\, with corresponding trans-Planckian inflaton excursions. I
  will describe in this talk how\, however\, generic considerations of 
 quantum gravity prevent such mechanisms to generate the large field ra
 nges required for successful inflation\, thus putting the whole natura
 l inflation program in jeopardy. I will also critically address possib
 le loopholes of this “no-go” theorem and attempts to overcome it.
