Query: MSSM-like AdS Flux Vacua with Frozen Open-string Moduli   We construct supersymmetric Pati-Salam flux vacua in AdS from intersecting
D6-branes on T^6/(Z_2 x Z_2'). The models constructed have three generations of
MSSM matter plus right-handed neutrinos. Because the cycles wrapped by the
D-branes are rigid there are no extra massless fields in the adjoint
representation, arising as open-string moduli. However, we find that it is
problematic to break the Pati-Salam gauge symmetry to the Standard Model (SM)
while keeping the SM hypercharge massless.
