“…The depth and momentum intervals were chosen to match the published data of µ − flux growth curves by the MASS89 and MASS91 experiment [10,23]. Figure 9 shows the flux growth curves for (a) negative and (b) positive muons for several momentum bins.…”

“…There have been a lot of measurements of atmospheric muon flux at ground level as compiled in Ref. [13] and at the balloon altitudes [14,15,16,17,18]. Among them, we select the series of precise measurements of atmospheric muons by BESS at various altitudes; sea level [11], mountain altitude [19] and balloon altitude [20], with sufficiently small systematic and statistical errors.…”

Study of cosmic ray interaction model based on atmospheric muons for the neutrino flux calculation

We have studied the hadronic interaction for the calculation of the atmospheric neutrino flux by summarizing the accurately measured atmospheric muon flux data and comparing with simulations. We find the atmospheric muon and neutrino fluxes respond to errors in the π-production of the hadronic interaction similarly, and compare the atmospheric muon flux calculated using the HKKM04 [1] code with experimental measurements. The µ + + µ − data show good agreement in the 1∼30 GeV/c range, but a large disagreement above 30 GeV/c. The µ + /µ − ratio shows sizable differences at lower and higher momenta for opposite directions. As the disagreements are considered to be due to assumptions in the hadronic interaction model, we try to improve it phenomenologically based on the quark parton model. The improved interaction model reproduces the observed muon flux data well. The calculation of the atmospheric neutrino flux will be reported in the following paper [2].

“…The various parameters described above are given in Tables II and III. The final µ − intensities as a function of momentum for various atmospheric depths are shown in Figure 4 and given in Table IV. Also shown in the figure are the measurements of the MASS [10,11] and CAPRICE [14] experiments. The HEAT sample of 10327 µ − events collected during ascent is to be compared with the MASS samples of 2893 events (1989 flight) and 4471 events (1991 flight) and the CAPRICE sample of 4627 events.…”

“…This is relatively easy for negative muons, as negatively charged particles other than electrons are rare in air showers (and electrons are easily rejected), while non-interacting protons generate a large background for positive muons above ∼1 GeV. Such measurements have been made by a number of instruments, including the MASS [10,11], HEAT [12,13], CAPRICE [14], and IMAX [15] magnet spectrometers and older, less sensitive balloon payloads.…”

Energy spectra, altitude profiles, and charge ratios of atmospheric muons

We present a new measurement of air shower muons made during atmospheric ascent of the High Energy Antimatter Telescope balloon experiment. The muon charge ratio µ + /µ − is presented as a function of atmospheric depth in the momentum interval 0.3-0.9 GeV/c. The differential µ − momentum spectra are presented between 0.3 and ∼50 GeV/c at atmospheric depths between 13 and 960 g/cm 2 . We compare our measurements with other recent data and with Monte Carlo calculations of the same type as those used in predicting atmospheric neutrino fluxes. We find that our measured µ − fluxes are smaller than the predictions by as much as 70% at shallow atmospheric depths, by ∼20% at the depth of shower maximum, and are in good agreement with the predictions at greater depths. We explore the consequences of this on the question of atmospheric neutrino production.
