DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IFTWeb/1/">A
  Swampland Tour: From Global Symmetries to Axion Physics</a>\nby Matthew R
 eece (Harvard U.) as part of IFT-Madrid Webinars\n\n\nAbstract\nThe Swampl
 and program aims to distinguish effective quantum field theories that can 
 potentially arise within UV-complete quantum gravity theories (“the Land
 scape”) from those that cannot (“the Swampland”). The most well-esta
 blished such criterion is that theories of quantum gravity never have exac
 t global symmetries. I will discuss some generalizations and consequences 
 of this idea. In particular\, I will discuss work in progress (with Heiden
 reich\, McNamara\, Montero\, Rudelius\, and Valenzuela) on how axion field
 s often play a crucial role in banishing global symmetries from a theory\,
  with potential phenomenological implications.\n\nsend email to  iftweb101
