SUMMARY:Swampland conjectures and their phenomenological application\,
  Theory Seminar (High Energy/Cosmology)\, Pablo Soler\, Heidelberg Uni
 versity
DESCRIPTION:An enormous amount of four dimensional effective field the
 ories\, many of them with interesting phenomenological implications\, 
 can be obtained from compactifications of string theory. The set of th
 ese theories is known as the landscape of string theory. It has been s
 uggested that\, beyond this landscape\, there exist consistent-looking
  effective field theories that cannot be embedded into UV complete the
 ories of quantum gravity\, in particular into string theory. They are 
 said to belong to the swampland. In this talk I will describe some of 
 the conjectures that define the boundaries of the swampland and implic
 ations they have on phenomenology\, in particular in models of dark ma
 tter and inflation. When applied to axions\, the swampland program nat
 urally leads to the study of gravitational instantons and Euclidean wo
 rmholes. I will also review some of the properties and puzzles posed b
 y these exotic objects.
