### Speaker

The high mass and large width of the top quark corresponds to a Standard Model prediction for a lifetime shorter than the timescale for strong interactions, implying that the top quark decays before hadronisation. Therefore, properties such as the spin correlation in the $t\bar{t}$ system are transferred to the decay products. In this talk I will discuss the possibility of measuring this correlation with early ATLAS data.
