Abstract

We consider anomaly cancelations in Type IIB orientifolds on T⁴/Z_N with quantized NS-NS sector background B-flux. For a rank b B-flux on T⁴ (b is always even) and when N is even, the cancelation requires a 2^b/2 multiplicity of states in the 59-open string sector. We identify the twisted sector R-R scalars and tensor multiplets which are involved in the Green-Schwarz mechanism. We give more details of the construction of these models and argue that consistency with the 2^b/2 multiplicity of 59-sector states requires a modification of the relation between the open string 1-loop channel modulus and the closed string tree channel modulus in the 59-cylinder amplitudes.
