Descripción
Magnetic monopoles are hypothetical particles carrying magnetic charge. They are predicted to exist in most extensions of the Standard Model of particle physics. A wide range of masses is allowed for magnetic monopoles, leading to a broad speed range for a hypothetical flux of these relics of the Big Bang. A magnetic monopole passing through IceCube would produce light through several different physical processes depending on its speed.
An overview will be given of the methods and results of current and recently finished searches for magnetic monopoles in IceCube. A focus will be put on the two most recent searches for magnetic monopoles: firstly, a search above the Cherenkov threshold in ice where the dominant background consists of rare, extremely high energy astrophysical neutrinos. Secondly the first search for monopoles inducing luminescence light at low relativistic speeds. New limits were obtained which exceed previous analyses by orders of magnitudes.
