Particle Theory Group WWW home page, Mar. 20, 2002(D-branes: a special class of p-branes called Dirichlet p-branes or D-branes; their importance stems from the fact that they make it possible to study the excitations of the brane using renormalizable 2D quantum field theory of the open string instead of the non-renormalizable world-volume theory of the D-brane itself, thus making it possible to compute non-perturbative phenomena using perturbative methods)
