摘要：

We study the generic p-p' system in the presence of constant NS 2-form B-ij field. We derive properties concerning with the noncommutativity of D-brane worldvolume, the Green functions and the spectrum of this system. In the zero slope limit, a large number of Light states appear as the lowest excitations in appropriate cases. We are able to relate the energies of the lowest states after the GSO projection with the configurations of branes at angles. Through analytic continuation, the system is compared with the branes with relative motion. (C) 2000 Elsevier Science B.V. All rights reserved.
