Interpretation of the atmospheric muon charge ratio in MINOS
MINOS is the first large magnetic detector deep underground and is the first to measure the muon charge ratio with high statistics in the region near 1 TeV.\cite{bib:adamson} An approximate formula for the muon charge ratio can be expressed in terms of $ε_π$ = 115 GeV, $ε_K$ = 850 GeV and $\ec$. The implications for K production in the atmosphere will be discussed.
