Search for a new light particle produced in association with a top quark pair with the ATLAS Detector

This thesis presents the first dedicated search for a new light pseudoscalar particle decaying into a pair of muons, and produced in association with a top quark pair. Pseudoscalars are well motivated phenomenologically in various theories beyond the Standard Model of particle physics, such as 2HDM+...
