Novel Methods for Particle Energy Reconstruction with the MAGIC Experiment — •Lukas Lütke-Lengerich, Simone Mender, and Dominik Baack for the MAGIC collaboration — TU Dortmund, Germany

The MAGIC telescopes, two Imaging Air Cherenkov Telescopes at La Palma, are sensitive in the energy regime from the GeV to the TeV range and are extremely capable instruments for studying gamma*ray sources in the Universe. With a ratio of photons to hadrons up to 1:10000 for the detected showers, it is crucial to understand the properties of all the particles for an improved background rejection and diverse scientific studies. In this talk, two novel methods for the energy regression are presented and compared, applicable to improve the characterization of all species of primary particles. While the first method uses look-up tables to estimate the particles* energy, the second approach is based on a random forest algorithm.
