Research Abstract

Cosmic rays are high energy particles coming from outside of the earth, and their energies can be higher than those realized by accelerators on the earth. They are thought to be protons or nuclei, and induce "air showers" through collisions with nuclei in the atmosphere. In this project, we aimed to make a new simulation code for air showers based on new theoretical development on high energy hadron scattering. The new theory is called "Color Glass Condensate", and we have constructed an event generator "CGC+HIJING model" which describes the first collision event for the development of air showers.
