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
for
, 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.
