Open String Axiverse
October 20 | 15:00 - 16:15
Speaker: Giovanni Villadoro from ICTP
Venue & Time: Red Room / 15:00
Abstract: Localized charged fields are a general feature of many realistic string compactifications. I will review how in four dimensions they can lead to a multitude of perturbatively-exact global symmetries that, when spontaneously broken, generate a new axiverse compatible with post-inflationary evolutions.
