Dynamical field range and mass hierarchies
Time: 2:00 pm - 3:25 pm
Place: 5280 Chamberlin Hall
Speaker: Aitor Landete, University of Wisconsin-Madison
Abstract: Several swampland conjectures suggest that there is a critical field range beyond which the effective field theory description breaks down in quantum gravity. In this talk we will review applications of these conjectures to axion monodromy models. We argue that the field range of interest is the field space distance traced by the physical trajectory that solves the equations of motion. A sufficiently large mass hierarchy can delay the breakdown of the effective field theory and allow simple techniques of moduli stabilization. In absence of such hierarchy multi-field techniques should be used. We illustrate these subtleties in Type II string compactifications.
