The cosmic ray muon spectrum and charge ratio in CosmoALEPH

Hadronic Scaling and the Charge Ratio of Cosmic Ray Muons

The charge ratio of cosmic ray muons produced by meson decay has been calculated with the assumption of scaling for high energy hadronic interactions. The values obtained are in good agreement with experimental results for muons coming from primary collision energies up to 40 TeV. This agreement and the observed near energy independence of the measured charge ratios support the scaling hypothes...

Cosmic Ray Muon Physics

We present a review of atmospheric and underground muon flux measurements. The relevance of these data for the atmospheric neutrino flux computation is emphasized. Possible sources of systematic errors in the measurements are discussed, focusing on the sea level muon data. Underground muon data are also reported.

Cosmic Ray Muon Detection

Cosmic Ray Muons and the Muon Lifetime

Four scintillation paddles and coincidence techniques are used to determine the overall flux and angular distribution of cosmic ray muons. The muon lifetime is measured using rare events where, after passage of a muon into a scintillator is detected, its decay is also detected a short time later. The distribution of the decay times provides information about the average muon lifetime. Statistic...

The Cosmic Ray Muon Flux at WIPP

In this work a measurement of the muon intensity at the Waste Isolation Pilot Plant (WIPP) near Carlsbad, NM, USA is presented. WIPP is a salt mine with a depth of 655 m. The vertical muon flux was measured with a two panels scintillator coincidence setup to Φvert = (3.10 +0.05 −0.07) 10 −7 s−1cm−2sr−1.
