Abstract:
Our knowledge of the fundamental particles derives from a detailed study of their properties. In this work, attention is directed towards the behavior of the more energetic particles in extensive air showers. Study of the various components (the electromagnetic component, the hadronic component and the muonic component) of the air shower particles is one powerful way in which it was found that what we know and what we assume. One of the main tasks is to determine the energy spectrum of the nucleons in cosmic rays in the Earth’s atmosphere. This fact was interpreted as showing that the ultra high energy cosmic ray particles are believed to be of extragalactic origin. Finally, it is convenient to introduce assumptions about particle interactions because there is a great deal of information about the strong interactions of the nucleons and about the nature of the cosmic rays.
