Riassunto (Inglese)

Riassunto (Italiano)

The ATLAS experiment will start taking data at the end of 2007.
During the very first data taking period it will be possible to make a preliminary measurement of the top quark mass in the semileptonic decay channel of ttbar events. A possible strategy to perform this measurement is presented with particular interest in the role of jet energy scale: a jet calibration algorithm is developed and results are discussed. A detailed discussion of test beam data is also presented together with comparisons of Monte Carlo predicions.
