Cosmic-ray muon fluxes deep underground: Intensity vs depth, and the neutrino-induced component

Abstract: The angular distnbution of muons observed deep underground (10788 ft, or 8.89 X 10' g~r n -~ standard rock) has been measured with a 174-m' liquid scintillation detector in conjunction with 48384 neon flash tubes. The data are fitted by a curve giving the vertical intensity of muons vs vertical depth h, asern-' sec-' sr-', and y = (7.58 k0.09) X lo4 g cm ' . The constant term, representing the measured depth-independent flux of muons produced in the surrounding rock by interactions of cosmic-ray neutrinos gene… Show more

“…Muons from primary cosmic ray interactions in the upper atmosphere penetrate the planet to great depths [ Crouch et al , 1978], causing background in geoneutrino observatories. Although an energetic muon loses energy (∼2 MeV/cm) primarily through interactions with atomic electrons, it is the occasional collision with an atomic nucleus that produces background to the geoneutrino signal.…”
