The Top quark is the heaviest of the known elementary particles and its high mass sets it apart from the other quarks. A precise measurement of the Top quark mass helps to constrain the allowed mass range for the Higgs boson. Understanding the Top quark's properties is also important for the future LHC experiments, as Top production will be a significant background process for searches for physics beyond the Standard Model.

Hendrik Hoeth detemines the Top mass from hadronic decays of Top pairs recorded by the DØ experiment at Fermilab during the Run-IIa period. For the event selection he uses kinematic cuts and a topological likelihood discriminant. For extracting the mass he compares the data with a signal + background hypothesis.

The hadronic decay channel is characterized by an overwhelming background of QCD multijet events which Monte Carlo generators fail to describe. A key result of Hoeth's work is the development and verification of a novel background model based exclusively on data.

This book is aimed at researchers with interests in particle physics and collider based experiments.
