Query: On the efficiency of the evaluation of the primary cosmic ray
  composition using lateral distributions of air shower electromagnetic
  component   New analysis of lateral distributions (LD) of electrons, muons and charged
particles in extensive air showers generated by $10^{15}-10^{19}$ eV cosmic
rays has been made with respect to the scaling formalism for LD and air shower
universality paradigm. It is found that lateral distributions of electrons and
muons, when considered separately, are well described by one-parametric scaling
functions, while for the charged particles mixture distributions the scaling
description is not accurate in radial distance range where electrons and muons
give a comparable contribution to the local particle densities. The use of
scaling formalism enables enhancing the electron/muon separation capabilities
and, when combined with theoretically motivated air shower universality
concept, provides robust mass composition estimates. The proposed approach
could be implemented for the present and future (multi-) hybrid air shower
observations, especially in realizing the potential of Auger and Telescope
Array observatories upgrades, as well as for re-analysis and cross-calibration
of the data collected from different air shower arrays in a broad primary
energy range.
