A dynamical surface which spans p + 1 spacetime dimensions, containing gauge group and charged matter, on which open strings (with Dirichlet boundary conditions ) can end. Dp-branes couple to Ramond-Ramond antisymmetric tensors of rank p + 1, generalizing the interaction of charged particles with the electromagnetic field. They were originally found as classical solutions of supergravity theories. In superstrings , there are stable (BPS) branes preserving 1/2 of supersymmetry charges . There are D7,D5,D3,D1 and D(-1) branes for Type IIB strings, D8,D6,D4,D2 and D0 branes for Type IIA strings and D9,D5 and D1 branes for Type I superstrings . There exist also non-BPS branes, for example D8,D6,D4,D2 and D0 branes for Type IIB and D7,D5,D3,D1 and D(−1) branes for Type IIA strings. D-branes are embedded in an underlying space of dimension ten for superstrings . Analogous branes exist in M-theory and are called M-branes , the BPS ones being the M5 and the M2 branes.
