Towards a Swampland Global Symmetry Conjecture using Weak Gravity
Tristan Daus, Arthur Hebecker, Sascha Leonhardt +1
It is widely believed and in part established that exact global symmetries are inconsistent with quantum gravity. One then expects that approximate global symmetries can be quantit…

A Conjecture on the Minimal Size of Bound States
Ben Freivogel, Thomas Gasenzer, Arthur Hebecker +1
We conjecture that, in a renormalizable effective quantum field theory where the heaviest stable particle has mass , there are no bound states with radius below (Bound Sta…

Thraxions: Ultralight Throat Axions
Arthur Hebecker, Sascha Leonhardt, Jakob Moritz +1
We argue that a new type of extremely light axion is generically present in the type IIB part of the string theory landscape. Its mass is suppressed by the third power of the warp…
