High-energy lepton, photon and air shower simulations using PROPOSAL — Jean-Marco Alameddine1, •Pascal Gutjahr1, and Alexander Sandrock2 — 1Astroparticle Physics WG Rhode, TU Dortmund University, Germany — 2Faculty of Mathematics and Natural Sciences, University of Wuppertal
In modern physics experiments, simulations are crucial to apply modern analysis methods to the obtained data. One prime example in astroparticle physics is the simulation of extensive air showers, whose signatures can either be signal or background for experiments that needs to be separated.
PROPOSAL is a customizable C++ and Python library, providing three-dimensional simulations of charged leptons and high-energy photons. One of many applications of PROPOSAL is within the currently developed shower simulation framework CORSIKA 8, the successor of the well-established software CORSIKA 7. For CORSIKA 8, PROPOSAL is used as a library to describe the electromagnetic and muonic shower component.
In this contribution, the basic concepts of PROPOSAL are introduced. Furthermore, validations of electromagnetic showers simulated with CORSIKA 8 are presented, which are obtained by comparing relevant shower parameters such as longitudinal and lateral profiles with CORSIKA 7 simulations.
