We compute the annulus diagram corresponding to the interaction of afractional D3 brane with a gauge field on its world-volume and a stack of Nfractional D3 branes on the orbifolds C^2 /Z_2 and C^3/Z_2 x Z_2. We show thatits logarithmic divergence can be equivalently understood as due either tomassless open string states circulating in the loop or to massless closedstring states exchanged between two boundary states. This follows from the factthat, under open/closed string duality, massless states in the open and closedstring channels are matched into each other without mixing with massive states.This explains why the perturbative properties of many gauge theories living onthe worldvolume of less supersymmetric and nonconformal branes have beenrecently obtained from their corresponding supergravity solution.Comment: LaTeX, 28 page
