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...
متن کاملCosmic 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...
متن کاملCharge ratio of muons from atmospheric neutrinos
We calculate the intensities and angular distributions of positive and negative muons produced by atmospheric neutrinos. We comment on some sources of uncertainty in the charge ratio. We also draw attention to a potentially interesting signature of neutrino oscillations in the muon charge ratio, and we discuss the prospects for its observation (which are not quite within the reach of currently ...
متن کاملPredicting Neutron Production from Cosmic-ray Muons
Fast neutrons from cosmic-ray muons are an important background to underground low energy experiments. The estimate of such background is often hampered by the difficulty of measuring and calculating neutron production with sufficient accuracy. Indeed substantial disagreement exists between the different analytical calculations performed so far, while data reported by different experiments is n...
متن کاملThe Speed and Lifetime of Cosmic Ray Muons
We measure the mean lifetime and speed of cosmic ray muons at sea level using coincidence techniques with scintillation detectors. We find the mean speed v of muons traveling near normal to earth’s surface to be 29.8 ± 2.5 cm/ns, corresponding to βμ = 0.994 ± 0.08 and γμ of 9.14. Our result is in agreement with the accepted average speed of vμ, which is listed as between 0.994 or 0.998 dependin...
