  We present a preliminary study on the possibility to search for massive
long-lived electrically charged particles at the MoEDAL detector. MoEDAL is
sensitive to highly ionising objects such as magnetic monopoles or massive
(meta-)stable electrically charged particles and we focus on the latter in this
paper. Requirements on triggering or reducing the cosmic-ray and cavern
background, applied in the ATLAS and CMS analyses for long-lived particles, are
not necessary at MoEDAL, due to its completely different detector design and
extremely low background. On the other hand, MoEDAL requires slow-moving
particles, resulting in sensitivity to massive states with typically small
production cross sections. Using Monte Carlo simulations, we compare the
sensitivities of MoEDAL versus ATLAS/CMS for various long-lived particles in
supersymmetric models, and we seek a scenario where MoEDAL can provide
discovery reach complementary to ATLAS and CMS.
