Abstract
The OPERA detector at the Gran Sasso underground laboratory (LNGS) was used to measure the cosmic ray muon charge ratio Rμ=Nμ+/Nμ- in the TeV energy region. R μ is shown as a function of the "vertical surface energy" E μcosθ. A fit to a simplified model of muon production in atmosphere allowed the determination of the pion and kaon charge ratios weighted by the cosmic ray energy spectrum.File in questo prodotto:
