L. Pentchev et al., The muon lateral distribution function as a transformation of the height-of-origin distribution in hadronic extensive air showers, J PHYS G-NU, 25(6), 1999, pp. 1235-1248
Starting from the parametrized energy and transverse momentum spectra at th
e height of the muon origin taken from the simulations, the lateral distrib
ution function of the muons is represented within a simple geometry model,
as an integral transformation of the the height distribution of the muon or
igin. The kernel of this transformation depends on the energy threshold, sh
ower zenith angle and observation level depth, while it is universal for di
fferent primary types and primary energies in the knee region. The validity
of this representation is discussed in connection with the assumptions of
the model.
