A new measurement of the altitude dependence of the atmospheric muon intensity
J. J. Beatty, S. Coutu, S. A. Minnick +12
We present a new measurement of atmospheric muons made during an ascent of the High Energy Antimatter Telescope balloon experiment. The muon charge ratio mu+/mu- as a function of a…
