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...

description 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. Different signal to background ratios are tested. The range of the x_s values considered is from 20 to 50.
