Mass spectrum of type IIB flux compactifications — comments on AdS vacua and conformal dimensions

A bstract In this note we study the mass spectrum of type IIB flux compactifications. We first give a general discussion matrix for F-term vacua in four-dimensional $$ \mathcal{N} N = 1 supergravity theories and then specialize to Calabi-Yau orientifold compactifications presence geometric non-geometric fluxes. setting are AdS 4 which compute conformal dimensions operators dual scalar fields. For mirror-dual DGKT construction find that one-loop corrections complex-structure moduli space lead real-valued — only when ignoring these recover integer values previously reported literature. an example configurations more than mirror also obtain non-integer dimensions. Furthermore, argue stabilizing axio-dilaton asymptotic regions by fluxes implies at least one corresponding eigenvalues diverges.
