| Title: | Closed String Axions as Fuzzy Dark Matter |
| Date (JST): | Mon, Jun 26, 2023, 13:30 - 15:00 |
| Place: | Seminar Room A |
| Abstract: | I will review the nature and couplings of closed string axion appearing in string theory compactifications, and in particular discuss some details of a recent addition to the axion spectrum in type IIB string theory, the so-called ’thraxions’. I then explain how the closed string axion properties generically lead to appearance of a few light axion states capable of being Fuzzy Dark Matter (FDM). This leads to concrete predictions for the FDM abundance as a function of the light axion mass. |
