# CORSIKA 8 - Towards a modern framework for the simulation of extensive air showers

## TL;DR

CORSIKA 8 is a modern, flexible simulation framework for extensive air showers, built with C++ and Python to replace the legacy FORTRAN version and meet future astroparticle physics needs.

## Contribution

This paper introduces CORSIKA 8, a new open platform for particle cascade simulations, addressing limitations of the legacy FORTRAN version with modern programming techniques.

## Key findings

- Development of CORSIKA 8 is underway with promising progress.
- CORSIKA 8 offers enhanced flexibility and maintainability.
- The new framework aims to improve simulation precision in astroparticle physics.

## Abstract

Current and future challenges in astroparticle physics require novel simulation tools to achieve higher precision and more flexibility. For three decades the FORTRAN version of CORSIKA served the community in an excellent way. However, the effort to maintain and further develop this complex package is getting increasingly difficult. To overcome existing limitations, and designed as a very open platform for all particle cascade simulations in astroparticle physics, we are developing CORSIKA 8 based on modern C++ and Python concepts. Here, we give a brief status report of the project.
