Description
The top-quark mass is a fundamental parameter of the Standard Model.
We will motivate, why precision determinations of the top-quark mass
are important in the upcoming high-energy run of the LHC and discuss
the prerequisites in theory for the extraction of a well-defined mass
parameter in a given renormalization scheme.
We show that the top-quark's running mass in the MSbar scheme can be
extracted with good precision at next-to-next-to-leading order in QCD
and discuss a number of suitable observables.
