SUMMARY:GRASS Seminar: 'Axions\, Three-Forms\, and M-Theory'
DESCRIPTION:Gravity\, Supergravity and Superstrings (GRASS) Seminar \nSpeaker: Ziqi Yan (Niels Bohr Institute\, Denmark) \nVenue & Time: Red Room / 15:00 \nAbstract: Scalar fields with masses protected by global shift symmetries\, commonly referred to as axions\, are abundantly used in effective field theories in cosmology and particle physics. I will discuss a (4+1) dimensional braneworld construction for axion-like particles\, where a 3-brane is coupled to a flux in the fifth dimension orthogonal to the brane\, and its uplift to M-theory. From the (3+1)-dimensional perspective\, this construction generates a mass for the axion and matches previously known proposals based on the coupling between the axion and a three-form gauge field.
