Title: On The Finiteness of 6d Supergravity Landscape
Abstract:We consider supergravity theories with 8 supercharges in $d=6$.

We show that all the proposed anomaly free theories with unbounded number of massless modes are restricted to a finite subset and thus argue that there is an upper bound on the number of massless modes, consistent with the String Lamppost Principle.Read More
