Measurement of the underground atmospheric muon charge ratio using the
MINOS Near Detector

Περίληψη:
The magnetized MINOS Near Detector, at a depth of 225 mwe, is used to
measure the atmospheric muon charge ratio. The ratio of observed
positive to negative atmospheric muon rates, using 301 days of data, is
measured to be 1.266 +/- 0.001(stat)(-0.014)(+0.015)(syst). This
measurement is consistent with previous results from other shallow
underground detectors and is 0.108 +/- 0.019(stat + syst) lower than the
measurement at the functionally identical MINOS Far Detector at a depth
of 2070 mwe. This increase in charge ratio as a function of depth is
consistent with an increase in the fraction of muons arising from kaon
decay for increasing muon surface energies.
