Abstract 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 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 and, by the expected specific shower shape in the ECAL crystals. No evidence for magnetic monopole event is observed. We set a 95% confidence level up- per limit of 23.9 − 14.7 fb on the production cross-section of Dirac magnetic monopoles with mass between 500 GeV and 3000 GeV. In addition, another search for magnetic monopoles, performed with the MoEDAL experiment at the LHC, 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. Keyword: magnetic, monopole, quantization, Dirac, LHC, CMS. |
