| dc.description | Theoretical calculations predict a small fractional difference in energy loss for $μ^+$ and $μ^-$ of the order of $0.15 %$ at high energies. This is predominantly due to a $z^3$ term in an extended ionization $dE/dX$ relation, in analogy to the Barkas effect at low energies around the Bethe-Bloch maximum. The atmospheric muon energy spectrum is steeply falling off with approximately $E^{-3.7}$ and thus the small difference in $dE/dX$ between $μ^+$ and $μ^-$ at high energies results in an amplified charge asymmetry of about $0.6 %$ many thousand meters water equivalent deep underground. | |
