Abstract.

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 \(\char1263\cdot 10^{-16} cm^{-2} s^{-1} sr^{-1}\) for \(1.1\cdot 10^{-4} \le \vert\beta\vert \le 5\cdot 10^{-3}\), 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.
