BPS-saturated bound states of tilted p-branes in type II string theory

We find BPS-saturated solutions of M theory and type II string theory which correspond to (nonmarginally) bound states of p-branes intersecting at angles different from pi/2. These solutions are obtained by starting with a BPS marginally bound (orthogonally) intersecting configurations of two p-branes (e.g., two four-branes of type II string theory), performing a boost transformation at an angle with respect to the world volume of the configuration, performing T-duality transformation along the boost direction, S-duality transformation, and T transformations along the direction perpendicular to the boost transformation. The resulting configuration is a nonmarginally bound BPS-saturated solution whose static metric possesses the off-diagonal term which cannot be removed by a coordinate transformation, and thus signifies an angle (different from pi/2) between the resulting intersecting p-branes. Additional new p-branes are bound to this configuration, in order to ensure the stability of such a static, tilted configuration.
