AdS swampland conjectures and light fermions

We consider constraints on D-dimensional theories in MD, dSD and AdSD backgrounds in the light of AdS swampland conjectures as applied to their compactification in a circle. In particular we consider the non-SUSY AdS instability conjecture and the AdS distance conjecture. For MD and dSD vacua the re...

description We consider constraints on D-dimensional theories in MD, dSD and AdSD backgrounds in the light of AdS swampland conjectures as applied to their compactification in a circle. In particular we consider the non-SUSY AdS instability conjecture and the AdS distance conjecture. For MD and dSD vacua the results may be summarized by a light fermion conjecture which states that in theories with ΔD ≥ 0 and a positive first non-vanishing supertrace (−1)k+1StrM2k > 0, a surplus of light fermions with mass mf < Δ1/DD must be present.
