Recent developments for the high-energy lepton and photon propagator PROPOSAL — •Jean-Marco Alameddine1, Jan Soedingrekso1, Alexander Sandrock2, and Maximilian Sackel11TU Dortmund University — 2National Research Nuclear University MEPhI

The precise simulation of high-energy particles is a major task for many analyses in astroparticle physics. PROPOSAL is a Monte Carlo software, usable in both C++ and python, providing an easy to use and customizable environment to simulate high-energy muons, taus, electrons, positrons and photons. Its functionalities allow finding an adequate trade-off between simulation precision and performance.

In this talk, the recent developments of PROPOSAL are presented, including the implementation of electron, positron and photon propagation as well as a major code restructuring towards a more modular software. This provides the possibility to extract individual components of the propagation routine of PROPOSAL to be used in external frameworks or analyses. One application example is the air shower simulation framework CORSIKA 8, where it will be possible to use PROPOSAL as an electromagnetic interaction model.
