Description
The top quark is a fundamental constituent of the Standard Model. Its
properties are accurately predicted by the theory, except for its mass,
which remains a fundamental parameter of the SM. Since the start of the
Large Hadron Collider many million of top-antitop quark pairs are available
for study. With such a statistics, the physics of the top quark has entered
the precision era.
The main techniques used by the ATLAS experiment to reconstruct the top mass
are discussed.
