For the present standard scenario, optics settings have been developed which provide a transition energy according to gamma_{t}r=45.5 in order to avoid transition crossing during acceleration. At extraction energy the corresponding nonlinear momentum compaction and phase slip factors cause the formation of a so called alpha bucket. In this contribution we present the results of transverse beam loss tracking studies in the alpha bucket regime. The effects of momentum spread, magnet errors and residual closed orbit distortion are analyzed.
