Evaluation of minimum number of signal events needed to measure the x_s mixing parameter

The evaluation of the minimum number of signal events needed to measure certain value of the mixing parameter x_s in the decay channel B_s^0 -> D_s pi^+ -> phi pi^- pi^+ -> K^+K^- pi^- pi^+ is presented. In the study momentum and flight path resolutions are taken into account. D...
