Abstract

In this paper we present the results of a search for nuclearites in the penetrating cosmic radiation using the scintillator and track-etch subdetectors of the MACRO apparatus. The analyses cover the beta =v/c range at the detector depth (3700 hg/cm2) 10-5 < beta < 1; for beta = 2 x 10-3 the flux limit is 2.7 x 10-16 cm-2 s-1 sr-1 for an isotropic flux of nuclearites, and twice this value for a flux of downgoing nuclearites.
