We consider D-particles coupled to the CGHS dilaton gravity and obtain theexact wormhole geometry and trajectories of D-particles by introducing theexotic matter. The initial static wormhole background is not stable afterinfalling D-particles due to the classical backreaction of the geometry so thatthe additional exotic matter source should be introduced for the stability.Then, the traversable wormhole geometry naturally appears and the D-particlescan travel through it safely. Finally, we discuss the dynamical evolution ofthe wormhole throat and the massless limit of D-particles.Comment: 16 pages, 3 figures, revte
