Measurement Of The Top Quark Mass With The ATLAS Detector At LHC

At the LHC, one of the Standard Model fundamental parameters that will be measured with high accuracy, is the mass of the top quark. About 8 million ttbar pairs are expected to be produced per year at low luminosity, so that the error on the determination of m_top will be dominated by systematics. I...

description At the LHC, one of the Standard Model fundamental parameters that will be measured with high accuracy, is the mass of the top quark. About 8 million ttbar pairs are expected to be produced per year at low luminosity, so that the error on the determination of m_top will be dominated by systematics. In this note, the contribution to the systematic error from the Monte-Carlo modelling and reconstruction algorithm, is evaluated. The production of ttbar pairs is simulated using Pythia, Herwig and Isajet generators. Different methods to reconstruct the W and the top mass are compared.
