- Аннотация: The value of \mu+/\mu- -ratio for atmospheric muons has been measured with the LVD detector, at the INFN Gran Sasso National Laboratory, Italy (minimal depth is 3000 m w.e.). To reach this depth muons should have an energy at the sea level higher than 1.3 TeV. The muon charge is determined studying the decay of stopping positive muons in the LVD iron structure and the decay of stopping positive and negative muons in scintillator. We obtain a ratio 1.26 +/- 0.11 +/- 0.04.
