"Multiple Muon Measurements with MACRO."https://hdl.handle.net/2144/40495The MACRO experiment at Gran Sasso provides means for detailed studies of multiple coincident penetrating cosmic ray muons. In this paper we concentrate on the studies of the ultrahigh energy primary cosmic ray composition using muon bundle multiplicities, muon pair lateral and angular separation distributions.en-USHigh energy physicsExperimentAstrophysicsPhenomenologyArticle495302
