The radio detection method for cosmic rays relies on coherent emission from electrons and positrons which is beamed in a narrow cone along the direction of the primary particle. Currently the only models to reproduce this emission with sufficient accuracy are Monte Carlo based simulations of the particle physics, which require large investments of computation time. Even then the final analysis relies on simple metrics and empirically determined correlations to retrieve quantities of interest.
The work presented here focuses on condensing the simulation results into a semi-analytical model, preserving the accuracy of the microscopic interactions while significantly reducing the computation time required for end-user analyses.
Going further one could use this knowledge to perform a tomographic reconstruction of the air shower, i.e. infer its development history only from ground-based measurements. This would open new avenues beyond the standard Xmax reconstruction, allowing more detailed analyses of individual air showers.
