Title: Deficit of the calculated muon flux at sea level for E{sub {mu}} {>=} 100 GeV: Analysis of possible reasons

Abstract

The reasons why a deficit of the calculated muon flux for E{sub {mu}} {>=} 100 GeV arises if use is made of data from direct measurements of the spectra of primary cosmic rays and present-day nuclear-interaction models are considered. It is shown that this problem may stem from significantly underestimating the primary-nucleon flux in balloon-borne experiments employing the technique of emulsion chambers. This procedure relies on an extrapolation of accelerator data; therefore, it is necessary to estimate, on the basis of various Reggeon models of hadron interactions, the systematic error introduced by this circumstance in the results of the measurements. Such an analysis would make it possible to refine the behavior of the spectra of primary cosmic rays, to reduce the methodological part of the error in the calculation of the fluxes of secondary cosmic rays in the atmosphere, and to draw more precise conclusions on the flaws in present-day interaction models without invoking new accelerator data.
