Measurement of the neutral D meson mixing parameters in D0 -> KSπ+π− decays

A model-independent measurement of the charm mixing parameters xD and yD in the D0 -> KSπ+π− decay mode is presented. The method uses ratios of yields in symmetric bins of the Dalitz plot and is binned in decay time. This is an alternative approach that does not require the knowledge of the phase...
