However\, as it stands it lacks a bottom-up explanation. Here we prove it under mild assumptions for locally symmetric moduli spaces\, by characteri sing the spectrum and geodesics that go to the boundary using just group-t heory concepts. With this\, we can compute exponential rate of decay of t he mass for any symmetric space and any representation of the spectrum\, s howing that the distance conjecture is always satisfied. Moreover\, assumi ng only one irrep\, we classify all groups and particle representations co mpatible with the decay rates of KK and string towers. Some of them are in the known landscape of string theory compactifications\, while a handful remain to be found or proven to be in the swampland.\n LOCATION:https://researchseminars.org/talk/AnLy/57/ END:VEVENT END:VCALENDAR
