Search for Magnetic Monopoles in the CMS experiment at the Large Hadron Collider (LHC).

A search for magnetic monopoles as an exotic long-lived particle, using a signature of a highly ionizing particle that deposits mostly of its energy in the Electromagnetic Calorimeter (ECAL) crystals, was performed with the CMS detector at the LHC using 33 $fb$$^{−1}$ of 13 $TeV$ proton-proton collision data. Monopole candidates were selected by reconstructing the trajectory of a highly ionizing particle in the tracking chamber, by the expected specific shower shape in the ECAL crystals. No evidence for magnetic monopole event is observed. We set a 95% confidence level upper limit of 23.9−14.7 $fb$ on the cross-section of Dirac magnetic monopole's production, with mass between 500 $GeV$ and 3000 $GeV$. In addition, another search for magnetic monopoles, has been performed with the MoEDAL experiment at the LHC and it is also mentioned. In particular, the results of the analysis of the data from the Magnetic Monopole Trapper with a precision SQUID magnet are discussed.
