This study, performed on simulated data, describes an untagged analysis of the Bd -> J/ѰK Ø* decay with the ATLAS detector during the low luminosity running period. This includes an analysis of the implementation and effect of different trigger strategies. One such trigger strategy uses a lifetime cut at the trigger level. It also describes the analysis of the Bd -> J/ѰK Ø* decay and its use in early studies of detector alignment. The Bd -> J/ѰK Ø* decay can be used to extract Øs, the weak mixing angle as well as the decay width difference ΔΓ. It is shown that it will be possible to make a measurement of ΔΓ with an integrated luminosity of just 200pb-1. The precision with which Øs can be measured is also calculated for different integrated luminosities ranging from 10-30fb-1.
