Charm Production by Cosmic Muons
Francesco Vissani
Abstract
Narrow muon bundles in underground detectors permit to study muoproduction reactions that take place in the surrounding rock. We analyze the relevance of a QED+QCD reaction, muoproduction of "open charm". The contribution to double muon events is estimated to be 4-8 % of the one due to QED "trident" process, for an ideal detector located under a rock depth of 3 km water equivalent, and an observation threshold of 1 GeV.
