Interpretation of the Underground Muon Charge Ratio

P. A. Schreiner, J. Reichenbacher, M. C. Goodman

The MINOS experiment has observed a rise in the underground muon charge ratio $r_{\mu }$ = ${\mu }^{+}/{\mu }^{-}$. This ratio can be related to the atmospheric production ratios of ${\pi }^{+}/{\pi }^{-}$ and…
