  In this paper, we investigate the transport through a T-shaped double quantum
dot coupled to two normal metal leads left and right and a superconducting
lead. Analytical expressions of Andreev transmission and local Density of
States of the system at zero temperature have been obtained. We study the role
of the superconducting lead in the quantum interferometric features of the
double quantum dot. We report for first time the Fano effect produced by
Andreev bound states in a side quantum dot. Our results show that as a
consequence of quantum interference and proximity effect, the transmission from
normal to normal lead exhibits Fano resonances due to Andreev bound states. We
find that this interference effect allows us to study the Andreev bound states
in the changes in the conductance between two normal leads.
