The precision on the measurement of the mass of the top quark has reached the level of about 0.3%, or 500 MeV. This is not an easy task, neither on the experimental front, for a particle whose final state includes jets and possibly neutrinos, nor from the theory point of view for a strongly interacting particle. Yet the high precision is needed because the top quark enters much of the dynamics of other particles and plays a crucial role in the electroweak symmetry breaking. This seminar will discuss the challenges of the top quark mass determination, and the recent advancements with the ATLAS experiment including direct measurements from the top decay and indirect determination from cross sections.
