Monopole and Exotics Detector at the LHC (MoEDAL) is a mostly passive detector located in the LHCb cavern, just outside LHCb detector. MoEDAL was designed to search for magnetic monopoles, but it also sensitive to long-lived charged particles.
A certain class of neutrino mass models predicts long-lived particles whose electric charge is four or three times larger than that of protons. Such particles, if they are light enough, may be produced at the LHC and detected. We investigate the possibility of observing those long-lived multi-charged particles with the MoEDAL detector.
