I'll review recent progress in the simulation of top quark production at the LHC. In particular, I will focus on event generators that describe the decay of the top quark beyond the LO accuracy. I will then discuss the importance of the radiative corrections in the top decay for observables potentially relevant for top mass determinations.
We prove for the simple case of hemisphere masses in e+e- annihilation that using a transverse momentum cut $Q_0$ on the evolution of parton showers based on coherent branching implies that the heavy quark mass parameter of the algorithm is not the pole mass, but differs from the pole mass by an amount proportional to \alpha_s(Q_0)Q_0$. The basis of the proof is (a) an analytic solution of...
The top quark mass is one of the most important parameters of the Standard Model, which therefore has to be determined very precisely. The LHC experiments dedicate entire analysis programs to deal with this task. Among various strategies, the template fitting method is one successful approach to extract the top quark mass from LHC data relying on top quark mass sensitive observables such as...
