We construct an MSSM-like model from intersecting D-branes in Type IIA theory on the Z 2 × Z ′ 2 orientifold where the D-branes wrap rigid 3-cycles. Because the 3-cycles are rigid, there are no extra massless fields in the adjoint representation, arising as open-string moduli. The presence of these unobserved fields would create difficulties with asymptotic(More)
