摘要：We discuss the possibility to observe matter e
ects in atmospheric neutrino
oscillations. The main conclusion is that an impact on the survival probability requires
the action of the MSW resonance, which becomes visible for baselines above 7000 km.
The associated muon charge asymmetry carries information on 13 and the sign of m2
31.
