“…It is important that in both cases there is a functional dependence R 0 (s), i.e. one-valued relation between parameters of shower lateral (R 0 ) and longitudinal (s) development stage representing the air shower universality [14,15]. One can see from Figure 2, that the rate of decrease of R 0 with energy is almost equal for two interaction models used in calculations.…”

“…On the basis of simulations using the simplified hadronic generator, it was also found [9,14,15] that the relation between the lateral shape of the electron distribution and the longitudinal shower age can be expressed by the R 0 (s) functional dependence, that is a consequence of shower universality properties [16].…”

On the basis of the scaling approach and CORSIKA simulations data the radial scale factor of lateral distribution of electrons in extensive air showers is confirmed as potentially effective primary mass estimator, and its sensitivity to hadronic interaction model is investigated. It is shown that improved composition results both on average and event-by-event basis can be achieved taking into account the universality property of air shower development expressed by the relation between radial scale factor and longitudinal age parameter. The enhancements of such a theoretically motivated tool for the unbiased cosmic ray composition deduction in a wide primary energy range from (multi-)hybrid air shower measurements of nearest future are discussed.

Abstract. On the basis of the scaling approach and CORSIKA simulations data the radial scale factor of the lateral distribution of electrons in extensive air showers is confirmed as a potentially effective primary mass estimator, and its sensitivity to hadronic interaction model is investigated. It is shown that improved composition results both on average and event-by-event basis can be achieved taking into account the universality property of air shower development expressed by the relation between the radial scale factor and the longitudinal age parameter. The enhancements of such a theoretically motivated tool for an unbiased cosmic ray composition deduction in a wide primary energy range for current and future (multi-)hybrid air shower measurements are discussed.

“…Consequently, variations of the shape of lateral distribution are totally described by rescaling the lateral distance. According to our calculations based on different methods and codes [19,20,40,45,46], the scaling approach is valid for the lateral distribution of electrons over the interval of scaling variable x = r/R 0 = (0.05−20), corresponding to the region of radial distances from r ∼ 10 m to r ∼ (2 − 4) km depending on shower age. The energy range where scaling formalism can be used extends up to 10 22 eV for electromagnetic showers taking into account Landau-Pomeranchuk-Migdal effect and interactions with geomagnetic field [19,20].…”

“…In this paper we report on the further development of the approach based on the air shower universality and scaling formalism for lateral distribution (LD) that exhibits the potential in improved primary composition evaluation from the 100% duty cycle surface detectors data [15][16][17][18][19][20][21][22].…”

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.
