Table 1 . Massless excitations of strings stretching between the branes indicated in the (cid:12)rst row organized in multiplets of the dimensional reduction of two-dimensional supersymmetry to zero dimensions in the second and third row respectively. Here VM denotes vectormultiplet, HM hypermultiplet, FM Fermi multiplet and CM chiral multiplet. Note that the system including the D2-branes only preserves corresponding to D0-D2 strings open. The last two rows list the charges of the mutliplets under the (cid:13)avor symmetry charges J and J l
