“…As a consequence, the relations between various shower characteristics represented using the cascade age parameter demonstrate to one degree or another the invariance with respect to the properties of a primary particle. Different aspects of the universality (phenomenology, possible generalisations, deeper understanding of the origin and limitations, sensitivity to the hadronic interaction model, applicability under conditions of real experiments) are subjected to remarkable interest [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39].…”

“…This led to various modifications of the NKG form, such as changing the values of exponents, introducing different constant or variable scale factors, lateral (s ⊥ ) or local (s(r)) age parameters and also generalizations of the function by using a third power-law term. A comprehensive review is beyond the scope of this paper (some discussions can be found in [33,34,36,38,44]).…”

“…The function of the form (4) was implemented by several groups for the description of LD of electrons, muons and charged particles in different energy and radial distance ranges (see e.g. [38,44,[47][48][49][50][51][52][53][54][55][56]). Nevertheless, the use of the shape of the lateral distribution to infer the mass composition is not straightforward due to the impossibility of high-precision measurements of the lateral distribution in a wide range of radial distances, the insufficient capabilities for effective discrimination of the electron contribution to the local densities of charged particles far from the shower core and also the limitations of the scaling approach itself.…”

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.

“…With the full coverage array operated in the ARGO-YBJ experiment at the 4300 m asl, very close to the shower maximum, for the first time the shower core region has been studied with unprecedented details [18]. In addition, events are selected on an event-by-event basis exploiting the lateral distribution of secondary particles and not the muonic size, with results nearly independent from the hadronic interaction models.…”

Extensive air shower (EAS) arrays directly sample the shower particles that reach the observation altitude. They are wide field of view (FoV) detectors able to view the whole sky simultaneously and continuously. In fact, EAS arrays have an effective FoV of about 2 sr and operate with a duty cycle of ∼100%. This capability makes them well suited to study extended sources, such as the Galactic diffuse emission and measure the spectra of Galactic sources at the highest energies (near or beyond 100 TeV). Their sensitivity in the sub-TeV/TeV energy domain cannot compete with that of Cherenkov telescopes, but the wide FoV is ideal to perform unbiased sky surveys, discover transients or explosive events (GRBs) and monitor variable or flaring sources such as Active Galactic Nuclei (AGN). An EAS array is able to detect at the same time events induced by photons and charged cosmic rays, thus studying the connection between these two messengers of the nonthermal Universe. Therefore, these detectors are, by definition, multi-messenger instruments. Wide FoV telescopes are crucial for a multi-messenger study of the Gravitational Wave events due to their capability to survey simultaneously all the large sky regions identified by LIGO and VIRGO, looking for a possible correlated γ-ray emission. In this contribution we summarize the scientific motivations which push the construction of new wide FoV air shower detectors and introduce the future instruments currently under installation. Finally, we emphasize the need of an EAS array in the Southern hemisphere to monitor the Inner Galaxy and face a number of important open problems.

“…The Nishimura-Kamata-Greisen (NKG) function [1,2] gives a good theoretical approach for the lateral distribution of electromagnetic particles, from which the dependency of the lateral growth of cascade on the energy, intensity and type of the primary cosmic rays can be clearly shown. Several ground-based observation experiments, such as ARGO-YBJ [3], KASKADE [4], NBU [5] and Utah neutrino detector [6], have reported the lateral distribution of secondary particles associated to the energy of primary cosmic rays. A few simulations have been done to study the lateral distribution.…”

For a high altitude experiment, the lateral distribution (particle density distribution) of secondary particles at detector level is an important parameter to get the information of primary shower event. During thunderstorms, the charged particles in extensive air showers will be accelerated or decelerated in strong atmospheric electric field. The intensity and the position of ground cosmic rays could be influenced. In this work, Monte Carlo simulations are performed by using CORSIKA to study the effect of thunderstorms electric field on the lateral distribution of charged particles at YBJ (4300 m a.s.l., Tibet, China). We found that the lateral distribution will be changed significantly in thunderstorm field. And the variation amplitude is found to be highly dependent on the electric field, the zenith angle of the primary shower event and the distance to the shower core. Our simulation results could be helpful in understanding the phenomena observed in ground based experiments (such as ARGO-YBJ) and the physical mechanism of secondary charged particles accelerated by thunderstorm electric field.
