| Abstract |
We analyze in detail the cancellation of U(1)-gauge and U(1)-gravitational anomalies in certain D=4 N=1 Type IIB orientifolds, from a string theory point of view. We verify the proposal that these anomalies are cancelled by a Green-Schwarz mechanism involving only twisted RR fields.By factorizing one-loop partition functions, we also get the RR couplings of D-branes and O-planes to theses fields.Twisted sectors with fixed planes participate to the inflow mechanism in a peculiar way.
