Search for cosmic ray point sources with the MACRO detector at Gran Sasso

Using a sample of 38.5 million underground muons collected by the MACRO detector we have performed an all-sky search for pointlike sourcesproducing excesses of muons above the expected background. The d.c. muon flux upper limit at the Earth coming from selected sources is of the order of 10^sup 13^...

Description
Summary:Using a sample of 38.5 million underground muons collected by the MACRO detector we have performed an all-sky search for pointlike sourcesproducing excesses of muons above the expected background. The d.c. muon flux upper limit at the Earth coming from selected sources is of the order of 10^sup 13^ cm^sup -2^ s^sup -1^ or less. Futhermore we discuss searches for possible modulated and variable sources of muons using differenttechniques.[PUBLICATION ABSTRACT]
