Čerenkov Photon Density Fluctuations in Extensive Air Showers
The details of Čerenkov light produced by a γ− ray or a cosmic ray incident at the top of the atmosphere is best studied through systematic simulations of the extensive air showers. Recently such studies have become all the more important in view of the various techniques resulting from such studies, to distinguish γ− ray initiated showers from those generated by much more abundant hadronic com...
متن کاملfor extensive air showers
The new hadronic Monte Carlo model QGSJET-II is applied for extensive air shower (EAS) calculations. The obtained results are compared to the predictions of the original QGSJET and of the SIBYLL 2.1 interaction models. It is shown that non-linear effects change substantially model predictions for hadron-nucleus interactions and produce observable effects for calculated EAS characteristics. Fina...
متن کاملNuclei cross sections in Extensive Air Showers
Abstract Cross sections for proton inelastic collision with different nuclei are described within the Glauber approximation. The significant difference between approximate “Glauber” formula and exact calculations with geometrical scaling assumption is shown for very high energy cross section calculations. According to obtained results values of proton–proton cross section reported by the Akeno ...
متن کاملA Heitler model of extensive air showers
A simple, semi-empirical model is used to develop the hadronic portion of air showers in a manner analogous to the well-known Heitler splitting approximation of electromagnetic cascades. Various characteristics of EAS are plainly exhibited with numerical predictions in good accord with detailed Monte Carlo simulations and with data. Results for energy reconstruction, muon and electron sizes, th...
متن کاملMultifractal nature of extensive air showers
Extensive Air Showers (EAS) [1] are produced when VHE/UHE primary photons ,protons and other high Z nuclei enter atmosphere from the top and produce Cherenkov radiation which can be studied by imaging technique or by measuring lateral distribution. Cherenkov images recorded by a TACTIC-like γ-ray telescope represents the two dimensional distribution of Cherenkov light pattern produced in the at...
