Search for nucleon decays induced by GUT magnetic monopoles with the MACRO experiment

Published

Journal Article

The interaction of a Grand Unification Magnetic Monopole with a nucleon can lead to a barion-number violating process in which the nucleon decays into a lepton and one or more mesons (catalysis of nucleon decay). In this paper we report an experimental study of the effects of a catalysis process in the MACRO detector. Using a dedicated analysis we obtain new magnetic monopole (MM) flux upper limits at the level of ∼ 3 · 10 -16 cm -2 s -1 sr -1 for 1.1 · 10 -4 ≤ |β| ≤ 5 · 10 -3 , based on the search for catalysis events in the MACRO data. We also analyze the dependence of the MM flux limit on the catalysis cross section.
