  We investigate transport properties through a crossbar-shaped structure
formed by a quantum dot (QD) coupled to two normal leads and embedded between
two one-dimensional topological superconductors (TSCs). Each TSC hosts Majorana
bound states (MBSs) at its ends, which can interact between them with an
effective coupling strength. We find a signature of bound states in continuum
(BIC) in the MBSs spectral function. By allowing finite inter MBSs coupling,
BICs splitting is observed and shows projection in transmission for asymmetric
coupling case as cuasi-BICs. As a consequence, we also show that the Fano
effect, arising from interference phenomena between MBSs hybridization trough
QD, is observed with a half-integer amplitude modulation. We believe our
findings can help to better understand the properties of MBSs and their
interplay with QDs.
