Abstract:
We check some consistency conditions for the D9-D\ol9 system in type I
string theory. The gravitational anomaly and gauge anomaly for
SO(n)×SO(m) gauge symmetry are shown to be cancelled
when n-m=32. In addition, we find that
a string theory with USp(n)×USp(m) gauge symmetry
also satisfies the anomaly cancellation conditions.
After tachyon condensation, the theory reduces
to a tachyon-free USp(32) string theory,
though there is no spacetime supersymmetry.
