Abstract

Gamma-hadron separation techniques are required for ground detections in the area of gamma-ray astronomy. The aim of this work is to implement and compare different separation methods for the next generation of detectors: the upcoming Cherenkov Telescope Array. Cut-based, logistic regression and decision trees were implemented and tested on simulated CTA detections. Then, their performance was compared, finding that decision trees outperform the rest of methods implemented, reaching around 95% of rightly classified as gamma-events. An even higher performance of these algorithms could be attained through further adjustments of the hyperparameters involved in their implementation.
