 Search for Magnetic Monopoles in the CMS experiment at the Large Hadron Collider (LHC). / Mai M. El Sawy 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 col [...] CERN-THESIS-2020-191 CMS-TS-2020-028. - 2020. - 255 p.
