SUMMARY:Extensions of a scale separation AdS$_4$ solution and their ma
 ss spectrum.\, Theory Seminar (High Energy/Cosmology)\, Georgios Tring
 as \, Annecy\, LAPTH
DESCRIPTION:In this talk we will discuss two extensions of the so-call
 ed DGKT solution\, a 4d scale-separated anti-de Sitter (AdS) solution 
 obtained as a compactification on a 6d torus orbifold. Each extension 
 consists in a specific large n expansion beyond the DGKT solution\, wh
 ere n is the unbounded F4-flux parameter. One of the extensions consid
 ered generalizes the known warped\, partially localized solution. We a
 nalyse the two extensions in 10d massive type IIA supergravity as well
  as in a 4d effective theory\, using a general warped compactification
  formalism. The main new correction to DGKT that we get is one from F4
 \, the other fluxes being constrained by flux quantization. In each ex
 tension\, one would expect corrections to the mass spectrum\, before r
 eaching contributions from alpha-prime corrections. However the mass s
 pectrum turns out to be robust and conformal dimensions remain unchang
 ed.
