Violation of the feynman scaling hypothesis and the cosmic-muon charge ratio: a model-dependent analysis

Summary We have attempted here to study the nature of the sea-level cosmicmuon charge ratio at very high energies on the basis of one particular model of multiple production of hadrons in which the violation of the Feynman scaling is one of the very gross features. It is found that extreme emphasis on this feature alone would cause drastic departures from the experimental values of the charge ratio; but when this is combined with some other recently observed and/or proposed characteristics of high-energy interactions the model-based calculations agree quite well up to several TeV energy regime with the data. The model, in the final analysis, supports a very feebly rising nature of the muon charge ratio at ultrahigh energy.
