Precise determination of muon shower content from shower universality property

Abstract

It is shown, that highly accurate estimation of muon shower content can be performed on the basis of knowledge of only vertical depth of shower maximum and total signal in ground detector. The estimate is almost independent on primary energy and particle type and on zenith angle. The study is performed for 21500 showers, generated with CORSIKA~6.204 from spectrum $E^{-1}$ in the energy range $\log 10(E)$ [eV]=18.5--20 and uniformly in ${\cos }^2\theta$ in zenith angle interval $\theta =0^{\circ }-65^{\circ }$ for QGSJET II/Fluka interaction models.
