New limits on magnetic monopoles searches from accelerator and nonaccelerator experiments

Abstract

Here, the status of the searches for “classical Dirac” magnetic monopoles (MMs) at accelerators and for GUT MMs in the cosmic radiation is discussed. We present recent analysis for classical Dirac monopoles at accelerators and the lowest flux upper limit for MMs in the mass range 105–1012 GeV obtained with the SLIM experiment at the Chacaltaya high-altitude-laboratory (5290 m a.s.l.).
